Add "make cmdcheck" to Lua script for l3kernel

This is a more-or-less direct reimplementation of "make checkcmds" from
the existing scripts: slgihtly different name as the check here doesn't
directlty relate to check/checklvt.

Note that this is a bit hard-coded, but as we only currently use for l3kernel
at present that is OK I hope.
