[poky] [PATCH 08/31] Hob: Adjust the progress bar and set 100% only when all is done.

[Scott Garman]

From: Shane Wang <shane.wang at intel.com>

After parsing recipes, Hob will populate recipes and packages, which is probably
time exhaused. So, this patch is to adjust the progress bar and ensure 100% is
set if and only if all populations are done.

The patch also fixes "weird 18 second delay when parsing recipes" on build appliance.
Because Hob is doing something, but the progress bar shows 100% and wait there.

[Yocto #2341]
