gpg: Remove --compress-keys and --compress-sigs feature.

* g10/gpg.c (oCompressKeys, oCompressSigs): Remove.
(opts): Turn --compress-keys and --compress-signs in NOPs.
* g10/options.h (opt): Remove fields compress_keys and compress_sigs.
* g10/export.c (do_export): Remove compress_keys feature.
* g10/sign.c (sign_file): Remove compress_sigs feature.
--

These features are disabled in GnuPG since the very early days and
they fulfill no real purpose.  For now we keep the command line
options as dummys.
