guest system gles fix: Enable screen capture with gpu on
Currently, when running emulator with gpu on, screen capture does not work.
This commit fixes that by doing the following steps:
1. enable gralloc to allocate buffer in gralloc_alloc for screen capture
usage mode.
2. read back screen pixels in gralloc_lock for screen capture usage mode
Note: This commit only fixes guest side, and to make screen capture work,
we also need the corresponding fix on host side in the following CL:
