Remove redundant constraints from libraries, discovered by -fwarn-redundant-constraints

This patch affects libraries, and requires a submodule update.

Some other libraries, maintained by others, have redundant constraints,
namely:
           containers
           haskeline
           transformers
           binary

I have suppressed the redundant-constraint warnings by settings in
           validate-settings.mk
(in this commit)
