rmdir: throw an error if operation fails and nargout == 0 (bug #57830).
* dirfns.cc (Frmdir): Change DEFMETHODX macro invocation to include nargout variable.
Check nargout, and for cases where "nargout == 0" and "status" indicates failure,
throw an error. For cases where "nargout > 0", return 3-value octave_value_list
in variable "retval".
* file-io.cc, gzip.cc, dir.m, isfolder.m, mkdir.m, run.m, tar.m,
unpack.m, zip.m, pathdef.m, savepath.m, configure_make.m, install.m,
uninstall.m, getpref.m, setpref.m, pkg.tst, publish.tst, system.tst:
Change calls from "rmdir" to "sts = rmdir" so that an error is not
unecessarily thrown in BIST tests and other clean up code.
