Fixes #13363: case of a meta not paying attention to being under binders.
In Evar := C[Meta] problems of unification.ml, and C[ ] contains
binders, Meta was wrongly considered by pose_all_metas_as_evars as
under these binders (while Metas are always defined in the initial
context of the unification problem).
