Cgroup root on dump

Otherwise in the error case, we end up subtracting two from the
static_args, which would lead to a segfault :)

This is almost never the right thing to use, and we don't use it any more
anyway.

We initialized cgfsng in a strange way inside of its implementation of
escape so we could use it during checkpoint. Instead, the previous patch
does a hacky initialization in criu.c, and we can get rid of the hacks
elsewhere :)

CRIU has added support for passing --cgroup-root on dump, which we should
use (see the criu commit 07d259f365f224b32914de26ea0fd59fc6db0001 for
details). Note that we don't have to do any version checking or anything,
because CRIU just ignored --cgroup-root on checkpoint before, so passing it
is safe, and will result in correct behavior when a sufficient version of
CRIU is present.

N.B. that these are only implemented in cgfsng, but,

15:28:28    tych0 | do we still use cgfs anywhere? or the cgm backend?
15:29:19 stgraber | not anywhere we care about

...I think that's okay.
