For modules we expect to be there, we need to --globals them in to avoid
linter errors. Maybe we should switch to a different model for these
to clean up our linter exceptions... 'meh'.

luacheck rightfully complains that i is unused in the show-module-options
loop at the end (it was used for some debugging in the process).
We've added a new pager module that's compiled in, so declare that as an
acceptable global.
We require some --globals due to custom loader extensions in our
environment. Add everything required for this to tools/boot so that other
interested parties can get up and go with linting our scripts and not get a
bunch of false-positives.
