udev hwdb: Support shipping pre-compiled database in system images
In some cases it is preferable to ship system images with a pre-generated binary hwdb database, to avoid having to build it at runtime, avoid shipping the source hwdb files, or avoid storing large binary files in /etc. So if hwdb.bin does not exist in /etc/udev/, fall back to looking for it in UDEVLIBEXECDIR. This keeps the possibility to add files to /etc/udev/hwdb.d/ and re-generating the database which trumps the one in /usr/lib. Add a new --usr flag to "udevadm hwdb --update" which puts the database into UDEVLIBEXECDIR. Adjust systemd-udev-hwdb-update.service to not generate the file in /etc if we already have it in /usr.
