par2script: don't bother removing already removed parts of arguments

the s/\@// conflicts with jenkins default directory naming for
concurrent builds and is wrong at this place/in this form:
0ce067c1fc334680a7d99e573ae8c2f3e623b645 already changed the format of
the parameter from @listfile to @@listfile, so stripping a single @ at
the front won't help at all.
Furthermore the stripping already was added to the
par2script/parameters.pm earlier, so the worker functions don't need to
deal with transforming commandline arguments.
