Since kernel 4.6, we can update kernel memory without
initialization, because it's accounted by default.

--root invocations make tests harder to read, and they only serve a very
specific purpose. As such, remove them from the `runc update` tests
because they don't serve a purpose.

On some systems, the cgroup hierarchies are grouped together
(cpu,cpuacct). In order to avoid fake failures, update the cgroup
parsing to just check whether or not the mountinfo options *contain* the
cgroup type.

URL. Fixes#794.

Previously we would apply seccomp rules before applying
capabilities, because it requires CAP_SYS_ADMIN. This
however means that a seccomp profile needs to allow
operations such as setcap() and setuid() which you
might reasonably want to disallow.
If prctl(PR_SET_NO_NEW_PRIVS) has been applied however
setting a seccomp filter is an unprivileged operation.
Therefore if this has been set, apply the seccomp
filter as late as possible, after capabilities have
been dropped and the uid set.
Note a small number of syscalls will take place
after the filter is applied, such as `futex`,
`stat` and `execve`, so these still need to be allowed
in addition to any the program itself needs.
