Android: add libmesa_nir dependency to libmesa_dricore

Commit 32fcced7b479 ("meta: Unset the textures_used_by_txf bitfield.")
added a dependency in libmesa_dricore to NIR headers, but failed to add
libmesa_nir as a dependency resulting in a build error:

In file included from external/mesa3d/src/mesa/drivers/common/meta.c:90:
external/mesa3d/src/compiler/nir/nir.h:48:10: fatal error: 'nir_opcodes.h' file not found

Add libmesa_nir as a static library dependency to libmesa_dricore.
