build: Always build gpgtar.

We use gpgtar to unpack test data, hence we always build it.  If the
user opts out, we simply don't install it.

* configure.ac: Add comment.
* tests/migrations/Makefile.am (required_pgms): Make sure gpgtar is
built.
* tools/Makefile.am: Always build gpgtar, but do not install it if the
user used '--disable-gpgtar'.
