common/gnttab: Introduce command line feature controls

This patch was originally released as part of XSA-226.  It retains the same
command line syntax (as various downstreams are mitigating XSA-226 using this
mechanism) but the defaults have been updated due to the revised XSA-226
patched, after which transitive grants are believed to functioning
properly.
