gnupg2: updated to 2.2.7

changes in version 2.2.7:
* gpg: New option --no-symkey-cache to disable the passphrase cache
  for symmetrical en- and decryption.
* gpg: The ERRSIG status now prints the fingerprint if that is part
  of the signature.
* gpg: Relax emitting of FAILURE status lines
* gpg: Add a status flag to "sig" lines printed with --list-sigs.
* gpg: Fix "Too many open files" when using --multifile.
* ssh: Return an error for unknown ssh-agent flags.
* dirmngr: Fix a regression since 2.1.16 which caused corrupted CRL
  caches under Windows.
* dirmngr: Fix a CNAME problem with pools and TLS.  Also use a fixed
  mapping of keys.gnupg.net to sks-keyservers.net.
* dirmngr: Try resurrecting dead hosts earlier (from 3 to 1.5 hours).
* dirmngr: Fallback to CRL if no default OCSP responder is configured.
* dirmngr: Implement CRL fetching via https.  Here a redirection to
  http is explictly allowed.
* dirmngr: Make LDAP searching and CRL fetching work under Windows.
  This stopped working with 2.1.
* agent,dirmngr: New sub-command "getenv" for "getinfo" to ease
  debugging.
