ANDROID: GKI: update gki defconfigs

Update the gki defconfig files based on upstream changes causing some
symbols to no longer be needed in the defconfig files.

This means the following symbols are removed for x86 and arm64 gki
defconfigs:
	CONFIG_MEMCG_SWAP=y
	CONFIG_MEDIA_CAMERA_SUPPORT=y

And the following only for arm64:
	CONFIG_MEDIA_CONTROLLER=y
