build: reduce explicit dependencies on macOS CoreFoundation

build: reduce explicit dependencies on macOS CoreFoundation

* src/local.mk: Revert v9.7-322-gc2e1816a5, instead relying
on the more focused v9.8-79-g532cd66af.  When built with
--disable-nls on macOS this will result in only some commands
being linked with INTL_MACOSX_LIBS, thus resulting in env(1)
at least not setting a __CF_USER_TEXT_ENCODING envirnoment variable.
