[Buildroot] [PATCH v2] package/systemd: use current tool for generating HWDB

[Norbert Lange <nolange79@gmail.com>]

udevadm has been deprecated for a while(for bulding the DB),
systemd-hwdb should be used in its place.

this tool further has a switch to generate the database in
/usr which is a better place for a one-time created file.

Also remove the config files from both paths
(rootfs overlay could add stuff) aswell as the service and tool
from the target fs.
