nspawn: add --suppress-sync=yes mode for turning sync() and friends into NOPs via seccomp

This is supposed to be used by package/image builders such as mkosi to
speed up building, since it allows us to suppress sync() inside a
container.

This does what Debian's eatmydata tool does, but for a container, and
via seccomp (instead of LD_PRELOAD).
