[OE-core] [PATCH 6/9] sstate_lockedsig.bbclass: add event handler to dump lockedsigs at recipe building time

[Hongxu Jia]

While the class in use, it adds a event handler at 'bb.event.BuildCompleted',
so after the build completed, it will dump the lockedsigs files.

Use SIGGEN_LOCKEDSIGS_CONFIG variable controls where to dump the lockedsigs file,
the default is placed into ${SSTATE_DIR}/locked-sigs.inc.
