Android: use FBO readback workaround by default.

Browse Source 
Maintaining a black list of devices can't be reasonably done.
The workaround is now enabled by default. It can be disabled with the
QT_ANDROID_DISABLE_GLYPH_CACHE_WORKAROUND environment variable, in
which case the current list of blacklisted drivers will still be taken
into account.
