Jiyong Park 016059dd46 Add /system/lib to the permitted paths for ns of APEXes
With b/144533348, there will be symlinks from libs in APEXes to the libs
in the system partition. This is to reduce the size of APEXes when the
APEX is bundled with the platform.

Adding the /system/lib to the permitted paths so that the realpaths of
the symlinks are allowed for the namespaces.

Note that this however does not open all libs in the system partition to
the APEX namespaces, because searching of the libs are NOT done in
/system/lib, but in /apex/<module>/lib directory.

# permitted paths because linker uses realpath(3) to check the accessibility
# of the lib. We could add this to search.paths instead but that makes the
# resolution of bionic libs be dependent on the order of /system/lib and
# /apex/.../lib/bionic in search.paths. If the latter is after the former,
# then the latter is never tried because libc.so is always found in
# /system/lib but fails to pass the accessibility test because of its realpath.
# It's better to not depend on the ordering if possible.
