Android: store resources on SD card.

Browse source 
On the first start Rockbox extracts libmisc.so which in fact is a zip file
holding resource files like theme bitmaps. Those can requires quite a bit of
memory.

As extended version of FS#12063 resources will now be extracted to SD card if
the file /sdcard/rockbox/rockbox-info.txt is found. This file is part of the
extracted resources and can therefore safely be used for checking.
