gpg: Install a dirmngr.conf file.
* g10/dirmngr-conf.skel: New. * g10/Makefile.am (EXTRA_DIST): Add file. (install-data-local, uninstall-local): Install that file. * g10/openfile.c (copy_options_file): Add arg "name", return a value, simplify with xstrconcat, and factor warning message out to: (try_make_homedir): here. Also install dirmngr.conf. * g10/options.skel: Remove --keyserver entry.
The option --keyserver in gpg has been deprecated in favor of
--keyserver in dirmngr.conf. Thus we need to install a skeleton file
for dirmngr to set a default keyserver.
