core: Extend gpgme_subkey_t to carry the keygrip.

* src/gpgme.h.in (struct _gpgme_subkey): Add file 'keygrip'.
* src/key.c (gpgme_key_unref): Free KEYGRIP.
* src/keylist.c (keylist_colon_handler): Parse GRP records.
* src/engine-gpg.c (gpg_keylist_build_options): Do not use
--with-fingerprint options for gpg versions >= 2.1.15.

* tests/run-keylist.c (main): Print subkeys and keygrips.
