utmp: favour POSIX utmpx over SVID utmp
Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the utmpx struct so this only changes the external API entrypoints and NOT the underlying data source. This saves about 500b (~1300b from previously ~1950) while at it. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
