Use gnulib version of canonicalize_file_name across all systems.

* configure.ac: Remove check for canonicalize_file_name since it is guaranteed
to be supplied by gnulib.

* file-ops.cc (octave_canonicalize_file_name): Simplify function by eliminating
#ifdef tree and just using gnulib version of function.

 dnl These checks define/undefine HAVE_FUNCNAME in config.h.
 dnl Code tests HAVE_FUNCNAME and either uses function or provides workaround.
