Support product-specific libraries

Product-specific libraries in /product/lib can be exposed to Android
apps by adding the list of the libs into
/product/etc/public.libraries-<companyname>.txt. The libs MUST be named
as lib<name>.<companyname>.so.

Bug: 73095206
Test: with taimen
mma -j and runtest.sh. The libs are all loaded in system, but not in
vendor. After reinstalling app using adb -r and reopening app, only
libraries listed in .txt are loaded
