The Zero variant won't build with the server or client also selected at the same
time, and expressing this in the Config.in would be too complicated to do.
Even so, selecting multiple variants doesn't seem to be that important in the
context of Buildroot.
This patch removes the ability to select multiple variants in favor
of just selecting one. The default is server as that is what all of the major
distributions currently use as the default as well.
