docs/android: Improve instructions for replacing driver 

"adb remount -R" doesn't actually remount partitions read/write, it just
enables the overlayfs and it needs to be followed by "adb remount" after
rebooting to actually remount.

Also, patchelf seems to work for changing the soname and is probably
better than hacking meson.build.
