[CRIU] [PATCHv3 4/6] criu(8): Document --lsm-profile

[Radostin Stoyanov]

The option --lsm-profile was added with commit:

 6af96c8404181e63d2424d1695fd7f8a42a291bf
 lsm: add a --lsm-profile flag

 In LXD, we use the container name in the LSM profile. If the container name
 is changed on migrate (on the host side), we want to use a different LSM
 profile name (a. la. --cgroup-root). This flag adds that support.

A usage example is available in
https://github.com/lxc/lxc/commit/13389b2963692a51162c703d8a64a79542b18949
