[PATCH] UML - fix utsname build breakage

[Jeff Dike]

Some -mm-only material leaked into a patch destined for mainline, and I didn't
notice.

This was the replacement of system_utsname with utsname() that's required by
the uts namespace patch.  This patch reverts those changes (which are correct
in -mm) so that mainline UML builds again.
