update libseccomp to 2.4.4, backport docker faccessat2 patch

libseccomp 2.4.4 and docker commit https://github.com/moby/moby/pull/41353/commits/a18139111d8a203bd211b0861c281ebe77daccd9 are required for faccessat2 support, which is required by alpine edge and is biting a lot of users. the latter is in 20.10.0, and is being backported in https://github.com/moby/moby/pull/41381, but we should probably do it now to stop the bleeding. i think these two should be backported to 3.12 at least, and considering that libseccomp is a x.x.X bump and docker is a simple patch, probably back to all supported alpine versions.
