Revert "cryptfs_hw:move libcryptfs_hw to system_ext"

This module was originally installed in product partition and
whitelisted in mainline_system.mk. If move to system_ext that
requires update the path in the mainline_system.mk whitelist.
This is a temp change and will be back to system_ext once
QSSI system pathing and system_ext partition changes are merged.

This reverts commit 85342b33a46a1e2d3f374f62ec27bebc5949a106.
