minigbm: Andorid.bp: Add intel varients to gralloc4

gralloc4 built with libminigbm_gralloc.so and gralloc0
with libminigbm_gralloc_intel.so, causes mismatch hence
leading to get_buffer failure during CTS tests.

The commit helps to have same instance of default libraries
shared between gralloc0 and gralloc4 and fixes get_buffer
failure on intel platform.
