maint: enable two checks

* cfg.mk (local-checks-to-skip): Enable two:
sc_prohibit_xalloc_without_use sc_two_space_separator_in_usage
* src/grep.c (usage): Conform: use two spaces, not 1.
* src/kwset.c (malloc): Define as a function-macro so that the
syntax-check rule sees that we are indeed using xmalloc here.
