utmp.h & utmpx.h for s390.


Hi folks,

All I can say is: he is right. I wanted to look into versioned symbols for
the glibc functions that are affected by the utmp.h/utmpx.h change but I
am too busy with other stuff right now (and I know that extreme caution
is required for anything to do with versioning).
I just copied the utmp.h/utmpx.h headers from powerpc/x86_64 to the s390
folder so credits go to Steven and Jakub.

blue skies,
  Martin.
