Add system_ext support to build_prop module

As some partitions have build.prop under etc/, this change adds
relative_install_path property to build_prop module. Also this change
adds system_ext related Soong variables and system_ext support in
gen_build_prop.py.

Bug: 322090587
Test: build and compare system_ext/etc/build.prop
