Fix up fd limit diagnosis code

Apparently Windows returns the "invalid argument" error code when the
path contains invalid characters such as '<'. The
test/Preprocessor/include-likely-typo.c test does this, so it was
failing after r368322.

Also, the diagnostic requires two arguments, so add the filename.
