Subject: afl-showmap: Allow @@ to be part of an arg

The previous implementation of "@@ handling"
in afl-showmap differed greatly from how it was
handled in afl-fuzz and how the documentation presented it.

It used to require that the @@ be its own argument separated
by whitespace and could not be used in situations like "--file=@@".

This change standardizes it to use detect_file_args() like
everybody else does, so that it will have the expected and
documented behavior.
