The runtime dependency on gnutls can be removed in the original recipe file
by just removing the RDEPENDS_{PN} line. If you want to do it in a bbappend
then this should work:
   RDEPENDS_${PN}_remove = "gnutls"
That should lead to gnutls not being automatically added to the image when
gnupg is added.

I think this change won't break anything but there's only one way to find
out...
