filesys.c: Fix readlink for ports on Darwin.

Browse source 
When passed a port, `readlink' relies on the Linux specific behavior of
empty c_path meaning "the fd itself".  That does not work on Darwin.
Since there is no branch that would yield both fd and c_path, fallback
to freadlink when __APPLE__ is defined.

* libguile/filesys.c (do_readlink): Call freadlink for !__APPLE__.
* configure.ac (AC_CHECK_FUNCS): Add freadlink.
