meta-ingrasys: Remove references to INGRASYSBASE

INGRASYSBASE 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-ingrasys rev: fcd2b2998a76f00307bb2ff821efa8ff8ef87c68)
