Do not install Android.bp file in recovery partition

https://r.android.com/3390999 accidentally led to the Android.bp file
being installed in the recovery partition. This change modifies the make
logic to ensure that the make generated recovery partition does not
install the Android.bp file.

Test: aninja -t query out/target/product/vsoc_x86_64/obj/PACKAGING/recovery_intermediates/ramdisk_files-timestamp && verify Android.bp is not included
