archive: raise error.Abort if the file pattern matches no files

Note that we could raise this exception even if no pattern were specified, but
the revision contained no files. However this should not happen in practice
since in that case commands.py/archive would exit earlier with an "no working
directory: please specify a revision" error message instead.
