maint: move man-related syntax checks in cfg.mk

This is more natural, now that the top-level Makefile has access to
all the variables and rules once defined only in 'man/Makefile.am'

* man/local.mk (all_programs, sc_option_desc_uppercase,
sc_man_file_correlation check-x-vs-1, check-programs-vs-x): Move
from here ...
* cfg.mk: ... to here.  Adjust some comments in the process.
