[GIT PULL] seccomp fix for v6.14-rc2

[Kees Cook]

Hi Linus,

Please pull this seccomp fix for v6.14-rc2. This is really a work-around
for x86_64 having grown a syscall to implement uretprobe, which has
caused problems since v6.11. This may change in the future, but for now,
this fixes the unintended seccomp filtering when uretprobe switched away
from traps, and does so with something that should be easy to backport.

Thanks!
