signcontrol: Remove it from the INN distribution

signcontrol is currently unconditionally installed even though it has per-site
configuration, so that configuration would be overwritten on "make update".
It does not need being shipped with INN.  For the rare people needing to
issue PGP-signed control articles, they can easily get it as part of the
pgpverify distribution available from ISC.
