[LTP] [PATCH v1] mpls01.sh: Add --allow-unsupported for modprobe

There are a couple of english words that contain "suse" as a substring
if one of these ends up in the os-release it would match, e.g. the
os-release may contain VERSION="24 (Disused Miracle)".  And yes both
Fedora and Ubuntu seems to include the the code names in the file.

So I would be stricter here and checked for ID=suse.
