opkg: Don't call sync() when installing into an offline root

Even when installing onto a live target system, calling sync() during
package installation is of somewhat questionable benefit.  But calling
it on the build host during rootfs construction is certainly useless and
can cause I/O to stall for several seconds on even a moderately sized
host which is clearly not desirable.

(From a patch originally by Mike Crowe.)
