[OE-core] [master][zeus][PATCH] sstate.bbclass: Only show sstate mirror progress bar for >= 100 objects

[Peter Kjellerstedt]

With the introduction of the hash equivalence server, the progress bar
for "Checking sstate mirror object availability" is shown
repeatedly. Most of the times the number of objects scanned is very
low and the progress bar completes almost immediately. To avoid all
these unnecessary progress bars, set the minimum number of objects to
100 before the progress bar is shown.

The minimum limit of 100 objects is of course quite arbitrarily
chosen, but it seems to do the job for me.
