Update some old selection script templates for modern dev mode

Copied the definition of isHostedMode() in from IFrameLinker's template, which is really the most up to date. Without this change, trying to run hosted mode on some of these linkers erroneously gives the "this module needs to be recompiled" message instead of the better "this linker doesn't support hosted mode".
