run-tests: find current version of aapt in folder rather than in PATH
The Jenkins server did not yet have 19.1.0 build-tools installed yet, so your fixed commits failed to build. This commit fixes the build:
Not everyone adds the build-tools to their PATH, so this makes it so this script will find aapt in the most recent build-tools version that is installed on the local system.

rsync improvements for fdroid server update
This is a couple of improvements to how `fdroid server update` uses `rsync`.
(also, please remove the branch when accepting any of my merge requests)
This allows the SSH key used to sync with the server to be specified via
the config.py or the command line. I need it for running automated tests
and setups.
rsync uses the modification time and size of the file when deciding whether
to update a file. These are relatively easy to control in malicious code,
so instead make rsync use a full MD5 checksum when decided whether the
index needs to be updated. I suppose we could add an option to use
checksum checking on all files, but since the signed repo already provides
a checksum check, it seems not worth the added load on the process.
Also, renamed 'index' to 'indexxml' to make it clear what is the XML and
what is the JAR.
Test updates and related bug fixes
I just set up some big tests of generating repos based on feeding as many random APKs into `fdroid update` as possible. On our jenkins server, the tests copy all of the APKs that the jenkins server has generated and builds a repo from them. This process caught lots of little glitches in the whole process. While these little glitches are usually caused by problematic APKs, `fdroid update` should handle them gracefully. Hopefully this set of fixes accomplishes that.
In this case, ANDROID_HOME is set to a fake, non-working version that will
be detected by fdroid as an Android SDK install. It should use the path
set by --android-home over the one in ANDROID_HOME, therefore if it uses
the one in ANDROID_HOME, it won't work because it is a fake one. Only
--android-home provides a working one.
It is not necessarily a good idea to try to distribute system APKs via
FDroid, but `fdroid update` should just ignore APKs it cannot handle rather
than die and prevent a repo from being fully created. This is necessary to
handle the automatic creation of repos, like for debug builds from a
Jenkins server.
Using this example app which does not have <uses-sdk>:
https://android.googlesource.com/platform/development/+log/master/samples/ApiDemos/assets/HelloActivity.apk
aapt then returns "sdkVersion:'IceCreamSandwich'". minSdkVersion is only
ever supposed to be an integer, so this is a bizarre APK. It is included
only as a binary in the git repo for Android sample code. But who knows
what else is out there, so report and error and carry on with the update
process.
