gpg: Improve the "secret key available" notice in keyedit.c

* g10/keyedit.c (KEYEDIT_NEED_SUBSK): New.
(cmds): Add this flag to keytocard, bkuptocard, expire, and passwd.
(keyedit_menu): Check whether only subkeys are available and take care
of that in the command check and in the HELP listing.  Also print a
different notice if only subkeys are available.
--

Print "Secret key is available" and the bailing out in all commands
which require the _primary_ secret key was surprising.  Now we print
another notice and adjust the checks.
