avoid test variant error output

If no variant is present, the diff script used to output a line like

numdiff: <bla>/tests/trilinos/precondition_muelu_q_iso_q1.with_trilinos>=11.14.with_64bit_indices=off.output.*: No such file or directory

because a glob in a for statement in bash will return it literally if no
files matches the pattern. This fixes it.
