selftests/mm: kvm, mdwe fixes to avoid requiring "make headers"

On Ubuntu 23.04, the kvm and mdwe selftests/mm build fails due to
missing a few items that are found in prctl.h. Here is an excerpt of the
build failures:

ksm_tests.c:252:13: error: use of undeclared identifier 'PR_SET_MEMORY_MERGE'
...
mdwe_test.c:26:18: error: use of undeclared identifier 'PR_SET_MDWE'
mdwe_test.c:38:18: error: use of undeclared identifier 'PR_GET_MDWE'

Fix these errors by adding a new tools/include/uapi/linux/prctl.h . This
file was created by running "make headers", and then copying a snapshot
over from ./usr/include/linux/prctl.h, as per the approach we settled on
in [1].
