Fix timegate's dependency on utils

The addition of dependencies in commit 52fc535d26
was incomplete, so loading the moremesecons_timegate mod can fail.

This change adds the moremesecons_utils dependency to those mods which
require the moremesecons table as reported by luacheck.
I've also made .luacheckrc more strict so that it sets globals per mod
and allows reading the moremesecons table only in mods which also have
the moremesecons_utils dependency.
