fmtutil-sys: finding a user cnf-file

[Norbert Preining]

Dear Ulrike,

> fmtutil-sys --cnffile=fmtutil-dev.cnf --all

This is not supported at the moment. Options passed via --cnffile need
to be fully specified paths for now.

But it sounds reasonable to support this, Karl, WDYT?

Ulrike, here is a patch for testing, it searches arguments passed via
--cnffile if they are not found directly, and not containing directories
(so only xxx.cnf, but not a/b.cnf).

Applies to texmf-dist/scripts/texlive/fmtutil.pl
