Add POSIX <utmpx.h>.
Now <utmpx.h> isn't any more useful on Android than <utmp.h> is, but it
is POSIX, and -- importantly -- we can implement it with just a header
file, so code can use it on every existing API level.
macOS does indeed only have the <utmpx.h> functions (although it does
still have the <utmp.h> header!), so potentially portable code might
want <utmpx.h> on Android. (glibc/musl both have both headers.)
