slurm_ctl_conf_t renamed in 20.11.X

[sandynomad]

the slurm 20.02.X structure slurm_ctl_conf_t was renamed to slurm_conf_t to 20.11.X

add a condition check for the Slurm version and then use the correct structure in the variable definition.

I guess it's always a good idea to check issues/pull requests of a project, I was about to do a pull request for this exact same reason, wasted some precious time for a simple
sed -i 's/slurm_ctl_conf_t/slurm_conf_t/g' test/slurm_ping.c
sed -i 's/slurm_ctl_conf_t/slurm_conf_t/g' slurm_drmaa/drmaa.c

Thanks! I'll get a release out for this shortly.
