sstate.bbclass: specify func dirs for sstate_hardcode_path
For some recipes that inhrient cmake, the ${B} may be removed by
cmake_do_configure() while sstate_hardcode_path() running, this
causes build errors:
Exception: OSError: [Errno 2] No such file or directory: \
'/path/to/build'
The function sstate_hardcode_path() called command:
$SSTATE_SCAN_CMD which extended as "find ${SSTATE_BUILDDIR} ..."
So the proper function dirs could be ${SSTATE_BUILDDIR}.
