Revert "Makefile: rework team compilation flags"

I don't think we should do this.

- renamining/dropping configure options is still an annoyance,
  because it requires to different ./configure options depending
  on the version. The rename from --enable-teamctl to --enable-team
  might be theoretically nice, but more annoying then helpful.

- There is no strict dependency between --enable-team and
  --enable-json-validation. At most, one could argue that
  when enabling the team plugin (--enable-teamctl), then
  libnm must also be build with --enable-json-validation.
  But in fact, the team plugin will happily work with a
  libnm that doesn't link against libjansson.
  That is --enable-teamctl --disable-json-validation will work
  in practice just fine.
  On the other hand, libnm is a client library to create connection
  profiles, fully supporting team profiles also makes sense if the
  actual plugin is not installed (or build). Thus, --disable-teamctl
  --enable-json-validation certainly makes sense.

At this point, one might ask whether libnm is even still complete without
libjansson. Maybe libnm should *require* --enable-json-validation.
But that is not what the patch was doing, and it would also need
some careful consideration before doing so.

This reverts commit 9d5cd7eae8.
