mail-filter/spamassassin: new revision to fix tests and improve init script.

This commit adds an upstream patch to fix a test suite crash with
newer versions of perl. It also largely rewrites the init script:

  * Don't conditionally "use mysql" or "use postgres" in the
    OpenRC init script. Even if SpamAssassin is installed without
    e.g. MySQL support, if MySQL is present on the system, a user
    might store his SpamAssassin data in it.

  * Use a declarative style and drop the custom start() and stop()
    functions.

  * Run the spamd daemon as the "spamd" user.

  * Use /run/spamd.pid for the PID file to avoid a "checkpath".

Some updates were made to the ebuild to facilitate those changes:

  * Don't modify the init script for USE=mysql or USE=postgres.

  * Create a "spamd" user in pkg_preinst().

Package-Manager: Portage-2.3.6, Repoman-2.3.1
