[PATCH] change config file used for hwclock-is-UTC setting

[Bill Nottingham <notting redhat com>]

So, ever since the dawn of time, hwclock has written whether the
system's hardware clock is in UTC or not to /etc/adjtime whenever
it saves the hardware clock, and reads that file whenever it
restores it.

Given that, it seems odd that we've been maintaining that state
in a separate file all this time. The following patches to
anaconda and system-config-date stop doing that.

While they are there, they also nuke the arc stuff, because
1) if hwclock doesn't support figuring that out automatically,
it should
2) the current Alpha ports of Fedora don't support any ARC console
machines any more, in any case
