Bug#996025: bullseye-pu: package libseccomp/2.5.1-1+deb11u1

[ Reason ]
libseccomp 2.5.1 only knows about syscall up to Linux 5.8.
The proposed changes add the syscalls up to Linux 5.14.
[ Impact ]
Syscalls for Linux 5.9 and 5.10 can't be allowed.
Software built with support for newer kernels (often the case in containers)
expect newer syscalls to work or return ENOSYS.
If that syscall is not supported by libseccomp and a default filter action of
returning EPERM is used, such software will break.
Therefore you often need to be able to allow a syscall even when the running
kernel doesn't support it.
[ Tests ]
* autopkgtest passes on amd64
* Verified adding a filter for the close_range() syscall works (new in 5.9)
* Verified that systemd and Docker run
[ Risks ]
The changes only extend the syscall csv table and add new syscall defines.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
Cherry-pick upstream commits to support syscalls up to Linux 5.14.
I've updated the debdiff to include two more cherry-picked patches that add
a new syscalls from Linux 5.15 and missing syscall defines.

+Subject: [PATCH] api: update seccomp-syscalls.h
+
+It appears that the seccomp-syscalls.h header file had gotten out of
+sync with the syscalls.csv syscall table, this patch fixes this
+disconnect.
+
+The only edit that is somewhat interesting is that the oldwait4(2)
+syscall probably never should have been included in the header file
+as it appears to no longer exist (?).

+Subject: [PATCH] syscalls: update the syscall table to v5.12-rc7
+
+Due to additional ABIs in main we can't do a simple backport or copy
+of the syscall table so we are generating it directly in the
+release-2.5 branch.
+
+This patch also fixes the missing faccessat2() #defines in the
+seccomp-syscalls.h header file.
