[OE-core] [PATCH 1/1] license.bbclass: optimize pkg runtime data

[Elizabeth Flanagan]

This fixes an ugly way I was trying to find pkg runtime
data for package and license manifest creation.

rootfs generation times for core-image-minimal:

Prior to patch
real	0m41.570s
user	1m40.466s
sys	0m6.768s

With patch
real	0m27.527s
user	0m9.833s
sys	0m3.496s
