Log Message:
chat/anope: Use gettext-lib and msgfmt. Default to gnutls over openssl.

Without gettext-lib and msgfmt being available, package creation fails
because the locale files aren't generated.

Similar reasoning for gnutls as inspircd - anope is based on an old
version of inspircd and is also GPLv2 with no exception for OpenSSL.
gnutls is the recommended TLS library for both.
