til: add til_get_module_names() helper

Composite modules that want to provide "all" aliases for modules
like rtv have to construct a comma-separated string of all module
names, usually filtered by some flags.

This helper does just that, but it does add yet another
open_memstream() user to revisit when those all get fixed up.
