metadata: parse.sh: Add -Itestcases/kernel/include

This does not completely fix macro expansions without the patchset I've
send that removes the mess in testcases/kernel/mem/{lib,include}/
library because before the patchset some headers e.g. the ksm_helper.h
was included indirectly from the testcases/kernel/mem/include/mem.h
header.
