#57591: creduce @2.7.0 does not use astyle

 creduce declares a dependency on astyle, with the comment:
 {{{
 # Not required at compile time, but the configure script checks for them.
 }}}
 That appears to have been true when creduce 2.5.0 was added to MacPorts,
 but I find no reference to astyle in creduce 2.7.0 anymore. I did not
 check the other so-marked dependencies; maybe they can be removed too.
