[LTP] [PATCH] tst_cgroup: Don't try to use V2 if V1 controllers are mounted

[Richard Palethorpe]

It is not possible to use a controller in V2 cgroups if it has been
mounted as a V1 controller. So if V1 is mounted we use it regardless
of if V2 is available.

We have to include a space in tst_is_mounted so that we do not match
cgroup2.
