v2:
 * Drop xenevtchn and xengnttab as well

This has been fixed in Xen 4.15 by the uselibs.mk logic, but 4.14 and older
cause everything linking against libxenstore to also try linking against
libxenctrl.  It also causes RPM to create unexpected dependencies between
subpackages, which is a problem when trying to separate the stable and
unstable libs.
