[PATCH 1/5] login: Consolidate utmp and utmpx headers

[Adhemerval Zanella via Libc-alpha <libc-alpha@sourceware.org>]

It moves the 'struct lastlog', 'struct utmp', and 'struct utmpx' to
specific files and consolidates the s390-32 utmp.h and utmpx.h headers.

Checked on x86_64-linux-gnu and i686-linux-gnu.  I also checked with
a build for s390-linux-gnu.
