Normalize filepath comment for gen files in build.prop
build.prop contains a `# from $filepath` comment to log the origin of a
sysprop. This is useful to have, but causes the metadata of
vendor/build.prop to be different between make and soong built
partitions. This CL replaces the absolute filepath of generated files
with their filenames in the build.prop comment.
Bug: 382295862
Test: commented out notice files in build/make/core/Makefile
Test: lunch aosp_cf_x86_64_phone-trunk_staging-userdebug
Test: export BUILD_DATETIME=10
Test: verified that vendor.img built by make and soong have the same
sha
