*.mk: gzip(1) doesn't need '-' to act as a filter

Remove the redundant special file name.  It would be better to specify
/dev/stdin, if we wanted to specify a file name.  But the command just
works as a filter without a filename, so there's no need for that at
all.  Remove this redundant code.

The other compressors are compatible with gzip(1) in that regard.  Do
the same.
