The new 'shared' and 'hugepages' controls aim to replace the 'file'
option in MemoryConfig. This patch also updated all related integration
tests to use the new controls (instead of providing explicit paths to
"/dev/shm" or "/dev/hugepages").

While testing self spawned vhost-user backends, it appeared that the
backend was aborting due to a missing system call in the seccomp
filters. mremap() was the culprit and this patch simply adds it to the
whitelist.

A few KVM ioctls were missing in order to perform both snapshot and
restore while keeping seccomp enabled.

On some systems, the open() system call is used by Cloud-Hypervisor,
that's why it should be part of the seccomp filters whitelist.

Both clock_gettime and gettimeofday syscalls where missing when running
Cloud-Hypervisor on a Linux host without vDSO enabled. On a system with
vDSO enabled, the syscalls performed by vDSO were not filtered, that's
why we didn't have to whitelist them.

This separates the filters used between the VMM and API threads, so that
we can apply different rules for each thread.

Based on the seccomp crate, we create a new vmm module responsible for
creating a seccomp filter that will be applied to the VMM main thread.
