Move default HAL libraries to vendor

Libraries under /hardware/libhardware/modules should go to /vendor/.

These are conventionl HALs for default implementations, most of them
are not used.

Camera and thermal are already moved in other CLs.

Bug: 35907904
Test: Compiled and checked install path. Verified on Sailfish with
$ lsof | grep default.
