[Android] Prefer binaries with extensions in make_apk.py.
[Android] Prefer binaries with extensions in make_apk.py.

When calling a binary such as Ant on Windows, we are currently
preferring the "ant" executable over "ant.bat", even though the former
is actually a shell script for Unix installations.

Change the preference order and check for binaries with extensions
first.
