[PATCH] xfsqa: call _notrun in common.dump if dump utils not found

[Eric Sandeen <sandeen@sandeen.net>]

it may not always be obvious to outsiders that xfsdump is packaged
separately from xfsprogs... is it worth checking for the binaries
rather than spewing verbose failures if it's not installed?

(and are the locations ok for irix/bsd/whatnot too...?)

... also abort if bc not found (common.filter requires this,
my minimal testing root didn't have it and much error spew
ensued... nicer to check up front IMHO)
