util-linux: bump to version 2.32

Leave both _VERSION_MAJOR and _VERSION to reduce churn. We are likely to
need _MAJOR on the next bump.

Drop ac_cv_header_sys_timex_h override; not needed with current
uClibc-ng.

Drop scanf_cv_type_modifier override; not used in configure script since
v2.21.

Drop upstream patch.
