2e4079becb build: Add libc to matrix for x86-64 tests 
To reduce issues caused by flaky tests split the musl and glibc jobs
into separate jobs. This means fewer jobs will need to be restarted for
flaky tests. This will also increase CI throughput since the musl builds
account for ~40% of the total CI time when run together with glibc.

09f3658999 vmm: Avoid zombie sigwinch_listener processes 
When a guest running on a terminal reboots, the sigwinch_listener
subprocess exits and a new one restarts. The parent never wait()s
for children, so the old subprocess remains as a zombie. With further
reboots, more and more zombies build up.

As there are no other children for which we want the exit status,
the easiest fix is to take advantage of the implicit reaping specified
by POSIX when we set the disposition of SIGCHLD to SIG_IGN.

For this to work, we also need to set the correct default exit signal
of SIGCHLD when using clone3() CLONE_CLEAR_SIGHAND. Unlike the fallback
fork() path, clone_args::default() initialises the exit signal to zero,
which results in a child with non-standard reaping behaviour.

We occasionally saw cloud-hypervisor crashed due to seccomp violations. The
coredumps showed the HTTP API thread crashing after it attempted to call
sched_yield(). The call came from rust stdlib's mpmc module, which calls
sched_yield() if several attempts to busy-wait for a condition to fulfil fall
short.

Since the system call is harmless and it comes from the stdlib, I opted to allow
all threads to call it.

Currently the only way to set the affinity for virtio block threads is
to boot the VM, search for the tid of each of the virtio block threads,
then set the affinity manually. This commit adds an option to pin virtio
block queues to specific host cpus (similar to pinning vcpus to host
cpus). A queue_affinity option has been added to the disk flag in
the cli to specify a mapping of queue indices to host cpus.
