49b49421d0 tests: Temporarily disable test_watchdog on aarch64
This test is very flaky and regularly causing CI failures. Until we can
identify the root cause we should disable this test.

See: #2103

e05ed9240a tests: Use raw images for all tests
Simplify our image handling by not copying both QCOW2 and raw images for
every test. Allow the test to choose QCOW2 or raw by specifying the
image name manually. A follow on patch will add explicity QCOW2 tests.

c91d25ea64 tests: Don't swallow SSH errors
When an SSH command fails we want to be able to see, via a panic() why
and where it failed. Replace use of .unwrap_or_default() from SSH
command calls to ensure that we can see the location of the panic.

Also enhance the existing SSH output code to show the error if there is
one.

f583aa9d30 sgx: update virt EPC device path and docs
Based on the LKML feedback, the devices under /dev/sgx/* are
not justified. SGX RFC v40 moves the SGX device nodes to /dev/sgx_*
and this is reflected in kvm-sgx (next branch) too.

Update cloud-hypervisor code and documentation to follow this.

14af74cb5b vmm: seccomp: Allow clock_gettime() on the vCPU thread
If the vCPU thread calls log!() the time difference between the call
time and the boot up time is reported. On most environments and
architectures this covered by a vDSO call rather than a syscall. However
on some platforms this turns into a syscall.

a4c076bd09 tests: integration: Don't always have kernel serial output
When doing a direct kernel boot only have console=ttyS0 in the command
line if we are explicitly testing the serial output. The default
behaviour is `--serial null` so this output will not be visible but will
trigger a KVM exit for every byte which is very costly when running
under nested virtualization.
