oci: respect process spec on exec
This patch fixes exec to use the original (start-time) process exec
configuration. Otherwise, we were creating a brand new spec process w/o
additional groups for instance.
Spotted while integrating CRI-O with cri-test...The test was failing
with:

sandbox: correctly init selinux labels

First, we weren't correctly initializing selinux labels. If any of
(level, user, role, type) was missing from kube selinux options, we
were erroring out. This is wrong as kube sends just `level=s0`
sometimes and docker itself allows `--security-opt label=level:s0`.
This patch directly initializes selinux labels, correctly, and adds a
test to verify it.

Signed-off-by: Antonio Murdaca <runcom@redhat.com>

test: testdata: use container_runtime_t selinux type

RHEL SELinux policy doesn't have `container_t` type but we're using it
in our fixtures. That means Fedora integration tests pass because
`container_t` is in Fedora's container policy but RHEL is broken.
Fix it by using `container_runtime_t` which is aliased in Fedora policy
to `container_t`.

822172a892 all: Switch from package syscall to golang.org/x/sys/unix
The syscall package is locked down and the comment in [1] advises to
switch code to use the corresponding package from golang.org/x/sys. Do
so and replace usage of package syscall where possible (leave
syscall.SysProcAttr and syscall.Stat_t).

  [1] https://github.com/golang/go/blob/master/src/syscall/syscall.go#L21-L24

This will also allow to get updates and fixes just by re-vendoring
golang.org/x/sys/unix instead of having to update to a new go version.
