ANDROID: GKI: Update owners for GKI modules lists

Add ramjiyani@ as per-file owner for:

android/abi_gki_protected_exports_*
android/gki_aarch64_protected_modules
android/gki_x86_64_protected_modules

Update required due to addition of multi arch support
caused renaming of these files with arch name in them.
