FIX: [droid] fix dvd playing on > 2Gb iso

This fixes playing DVD ISO on droid for those where VOB's exist above  2Gb
It's a bit empirical as I'm not actually sure how the emu_msvcrt thingy works ;)
Not sure whether it's the right place for the CFLAGS, either 

As for the equivalent Samba patch, the problem is that the Android NDK doesn't respect FILE_OFFSET_BITS=64, so lseek stays the 32bits one and is thus limited to 2Gb.
