crtools: write a pid of a root task in a specified file

Browse Source 
When we restore a pid namespace the root task will get some unknown pid
in the original (i.e. -- the ns crtools a launched from) one. To find
this pid out one can use this option -- it will make the pid obtained by
the new init to be written into a pid file.
