[4/4] busybox: Add USE flag to set whether busybox hwclock uses utc

From: Christian Sørensen <christian.braunersorensen@prevas.dk>

USE_busybox_hwclock_use_utc: Default not set. If set, inserts --utc to
all hwclock commands within the busybox-hwclock initscript.

For easier (re)configuration, on target, it would be better if you
configure a single variable in the busybox-hwclock script, and then use
that on all calls to hwclock.
