There are no new constants covered by tst-mman-consts.py,
tst-mount-consts.py or tst-sched-consts.py in Linux 6.13 that need any
header changes, so update the kernel version in those tests.
(tst-pidfd-consts.py will need updating separately along with adding
new constants to glibc.)
Tested with build-many-glibcs.py.
This patch updates the kernel version in the tests tst-mount-consts.py,
and tst-sched-consts.py to 6.11.
There are no new constants covered by these tests in 6.11.
Tested with build-many-glibcs.py.
