Without this, the build of e.g. psusan would fail on systems without that header (such as Termux on Android). This is similar to how things were pre-cmake, but not identical. We used to treat lack of updwtmpx() as a reason to OMIT_UTMP (as off0dfa73982), but usage of that function got conditionalised inc19e7215dd, so I haven't restored that exclusion.
