gpgv: Improve documentation for keyring choices

* doc/gpgv.texi: Improve documentation for keyring choices

--

From the existing documentation, it's not clear whether the default
keyring will always be mixed into the set of keyrings, or whether it
will be skipped if a --keyring is present.  The updated text here
attempts to describe the keyring selection logic more completely.
