base.bbclass: move invalid PACKAGECONFIG checking to insane.bbclass
There was a problem when check invalid PACKAGECONFIG in the anonymous
function (when parsing), for example, there are two versions of a
recipe:
foo_1.0.bb
foo_2.0.bb
While foo_2.0.bb has a "PACKAGECONFIG[item] = 'x,y,z'", but foo_1.0.bb
doesn't, if we set PACKAGECONFIG_pn-foo = "item" in a conf file, we
would get the warning about invalid PACKAGECONFIG for foo_1.0.bb. Delay
the checking to build time will fix the problem.
