afl-cmin: Allow @@ to be part of an arg

The previous implementation of "@@ handling"
in afl-cmin 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 just look for @@ to be *in* an argument
in the same manner that afl-cmin.bash does, so that it will have
the expected and documented behavior.
