[CRIU] [PATCH 1/2] dump: Rollback in case if -R option passed

[Cyrill Gorcunov]

It's been found that if -R (leave task running after checkpoint)
option passed we don't unlock network, nether we clean service
files (such as link remaps).

After a long discussion we choose the following path: if -R option
is passed, it means a user is quite confident in what he is doing
and consistency of the resources (file system) is achieved by
a user himself with help of post-dump script. Also a user knows
that the network will be unlocked and accept such case.

So here we check of -R being passed in command line and once
checkpoint complete we unlock the network and cleanup remap
links if they were created durig checkpoint.
