[sknpm] Add modules instead of replacing them (#294)

The dark magic of `sknpm` replaces the line `/*--MODULES--*/` with
several lines of `import` followed by `modules = [...];`, expecting a
pre-existing `var modules = [];`.
Linters expect this line to be `const modules = [];` because the array
doesn't seem to be changed.
Fine, let's push modules instead of replacing the contents of the array,
which was brittle if we didn't start with an empty array.
