hplip: retain udev rules in WithPlugin version

Beginning with commit 8ffd6af2,
the build recipe for `hplipWithPlugin` explicitely drops a
udev rule file that is delivered with the sources.
In `hplip` (without plugin), the rule file is retained.

The udev rules takes care of uploading firmware
to certain printers (and maybe of other things),
e.g. to HP LaserJet 1000.

This commit reinstates the rule file and
expands the fixup script so that the rules
are also patched in the WithPlugin version.
