LU-10626 test: create custom udev rule

Some lustre developer do all their testing from their lustre
source tree instead of installing it into an image. Since lustre
is not installed into the image the udev rule for lctl set_param
doesn't work since its not in /etc/udev/rules.d. Additonally udev
rules require using the absolute paths for executables. To handle
this setup create a special udev rule on the fly using $LCTL to
be placed into /etc/udev/rules.d.
