fix(runtime): ordering of loading packages with user config

site packages must be sourced before user config

NOTE: we only consider dirs exactly matching "after" to be an AFTER dir.
vim8 considers all dirs like "foo/bar_after", "Xafter" etc, as an
"after" dir in SOME codepaths not not in ALL codepaths.
