[VAR] Do not poplocalvars prematurely on regular utilities
The recent cmdenviron removal broke regular utilities by calling
poplocalvars too early. This patch fixes that by postponing the
poplocalvars for regular utilities until they have completed.
In order to ensure that local still works, it is now a special
built-in.
