Flattened APEXes are installed in /<partition>/apex/<name>, so its
file_contexts file should be amended accordingly.
For example, file_contexts of an apex "com.android.foo" with should be
modified by prepending actual install path to the path regex.
/bin/foo <sepolicy label>
=> /system/apex/com\.android\.foo/bin/foo <sepolicy label>
File_contexts file is emitted to "make" via LOCAL_FILE_CONTEXTS variable
for apex_manifest.pb module.
Make collects these files and use them to build file_contexts.bin.
Also removed global state which is used to keep the list of all
flattened apexes.
Bug: 166518492
Test: m file_contexts.bin
check intermediate file_contexts.modules.tmp file
in $OUT/obj/ETC/file_contexts.bin_intermediates/
