[PATCH 2/4] test: due not pass T380.1 for the wrong reasons

[Michael J Gruber <git@grubix.eu>]

If gdb is missing then some files are never written to so that the
comparisons of non-existing files succeeds for the wrong reason,
claiming that `notmch new` is idempotent when it was in fact never run.

Catch this and (for lack of a better spot) set up the files with a
reason for the FAIL.
