sanity.bbclass: split out config re-parse check

Split out the functionality doing configuration re-parse check into a
separate event handler that is hooked into ConfigParsed event. This will
make config re-parsing actually work. Re-parsing in bitbake is triggered
by setting BB_INVALIDCONF whose value is checked after configuration has
been parsed (after ConfigParsed event). However, previously
BB_INVALIDCONF was set in SanityCheck event handler which caused
re-parsing never to happen.
