Update security/netpgpverify to version 20140202

Changes from previous version:

Add the ability for netpgpverify to verify ssh-pub-key-based signatures.

It is much more likely for ssh (rather than pgp) keys to be available,
and used, as a source of authentication data.  These changes add the
ability for netpgpverify(1) -- the standalone, zero-prereq utility -
to verify signatures made by netpgp when using ssh keys.

Running the regression tests in WRKDIR gives the following output:

A new HOWTO file is provided in the sources (files/HOWTO) to show how
to sign data using ssh keys and netpgp(1).
