xfstests: skip dump tests if dump utils not found
I was running xfstests on a NAS box which had no xfsdump,
and any tests which required xfsdump were failing in not-so-nice
ways:
+ xfsdump not found
038 [failed, exit status 1] - output mismatch (see 038.out.bad)
I think using _notrun is a lot better:
038 [not run] xfsdump not found
