busybox: disable hwclock
busybox: disable hwclock

Disable buysbox's hwclock entirely because we don't need it (save some
space) and also avoid symlink confusion by having one hwclock provider.

We need full hwclock functionality as provided by the util-linux-hwclock
package, but because the busybox one is enabled it gets picked up by
default as the whole distro is busybox-based and update-alternatives
is relied upon at rootfs creation or first boot (during ipk-postinsts)
or at manual update-alternatives calls to switch from busybox-hwclock
to util-linux-hwclock.

This leads to problems in certain situations when update-alternatives
gets things wrong (most probably it's mis-called during MAX install,
I've never actually spent time debugging what MAX does to screw up the
symlinks at install time) leaving the hwclock symlink pointing to
busybox instead of hwclock and leading to various failures of tests
depending on full util-linux-hwclock functionality.
