gpg: Remove incorrect %w from error string

The call we are reporting an error does not return an `error` value, the
`err` variable was set by the goOpenpgp.ReadArmoredKeyRing call.
 We should not include ("%w", err) in the error we return after a
goClearSign.Decode() failure as 'err' is nil anyway if we reach this
call.
