kernel/utsname_sysctl.c: Fix hostname polling
Commit bfca3dd3d068 ("kernel/utsname_sysctl.c: print kernel arch") added
a new entry to the uts_kern_table[] array, but didn't update the
UTS_PROC_xyz enumerators of older entries, breaking anything that used
them.
Which is admittedly not many cases: it's really just the two uses of
uts_proc_notify() in kernel/sys.c. But apparently journald-systemd
actually uses this to detect hostname changes.
