meta-yadro: Remove references to YADROBASE

YADROBASE is only used for pointing at licenses...point at the
licenses in oe-core in meta/files/common-licenses instead. to match the
defacto convention used in other oe layers like meta-openembedded.

(From meta-yadro rev: 55fa5d541e0cb4291c46213132b479e6d16e8360)
