Add *_dri.so symlinks to Android build recipe
What does this MR do and why?
Add *_dri.so symlinks to Android build recipe
Android changed so that every file ending up on the target needs a build
rule. This is also true for symlinks. Until now the *_dri.so symlinks
where generated in meson and where unconditionally copied into the
target image. Since 152cdfab7c2 in Android build/make this doesn't
happen anymore and needs fixing in mesa.
