This patch updates the kernel version in the tests tst-mman-consts.py and tst-pidfd-consts.py to 5.18. (There are no new constants covered by these tests in 5.18, or in 5.17 in the case of tst-pidfd-consts.py that previously used version 5.16, that need any other header changes.) Tested with build-many-glibcs.py.
