remove enable_remotejoin and enable_remotegroup C variables

None of those variables was referenced in C code, and there are
no GUC variables matching them, so it's a dead code.

Those variables are still referenced in three sets of regression
tests - rangefuncs, xc_limit and xc_sort.

For rangefuncs the reference is however only in one of multiple
possible outputs (and apparently we pick another one), and the
other two regression tests are not part of any test schedule.
