rcfile: report an error when an included file does not exist

Browse Source 
That is: do not silently return from parse_one_include() when the
given file does not exist, *and* return the filename (or pattern)
itself when it matches nothing.

This fixes https://savannah.gnu.org/bugs/?63446.

Bug existed since version 4.0, commit d3f0d32e.
