Cleaner solution to the problem fixed in r1445267.

* subversion/bindings/swig/perl/libsvn_swig_perl/swigutil_pl.c
  (svn_swig_pl_set_revision): Return a svn_opt_revision_t instead of using a
    pointer to a pointer.

* subversion/bindings/swig/perl/libsvn_swig_perl/swigutil_pl.h
  (svn_swig_pl_set_revision): Update declaration.

* subversion/bindings/swig/include/svn_types.swg
  (svn_opt_revision_t): Update typemap to match changes to
    svn_swig_pl_set_revision().
