TAL_TAKE provides a magic context meaning "consume my args and return

Several modules were only listed as dependencies because they were used in
the testcases.  That in turn gave some bogus incompatible license warnings
which we partially suppressed from _info.  Now that ccanlint supports
testdepends, use that to clean it up.

This allows us to separate dependencies only needed for testing.
This matters: they don't have the same impact on licensing, nor necessarily

relicensing you can otherwise get agreement to.
