[CRIU] [PATCH 5/5] tty: Add restoration of controlling terminal v2

[Cyrill Gorcunov]

The idea behind is pretty simple -- once we find
that there is a controlling terminal present we
do call ioctl on appropriate /dev/pts/N.

v2:
 - restore control terminals via service fd,
   still need to speedup service fd retrieval.
 - use prepare_ctl_tty() helper to generate
   control terminal fdinfo entry
