gralloc ashmem hack to delay cb close

Tired of public emulators not working with O

See this CL for context:

https://android-review.googlesource.com/#/c/372376/

This CL moves that to the guest, and detects if
each gralloc cb has been opened at least once
before allowing gralloc_free to call rcCloseColorBuffer.

Images using Treble / HIDL gralloc that have this CL
should work with older emulator versions.

Bug: 37302997

Test: Build and run sdk_google_aw_x86-userdebug emulator
