Update to 2.1.23, and use the correct TEST_TARGET.

• gpg: Options --auto-key-retrieve and --auto-key-locate "local,wkd" are now used by default. Note: this enables keyserver and Web Key Directory operators to notice when a signature from a locally non-available key is being verified for the first time or when you intend to encrypt to a mail address without having the key locally. This new behaviour will eventually make key discovery much easier and mostly automatic. Disable this by adding no-auto-key-retrieve auto-key-locate local to your gpg.conf.
• agent: Option --no-grab is now the default. The new option --grab allows to revert this.
• gpg: New import option "show-only".
• gpg: New option --disable-dirmngr to entirely disable network access for gpg.
• gpg,gpgsm: Tweaked DE-VS compliance behaviour.
• New configure flag --enable-all-tests to run more extensive tests during "make check".
• gpgsm: The keygrip is now always printed in colon mode as documented in the man page.
