[CRIU] [PATCH] crtools: Make sure the option has been strdup'ed

[Cyrill Gorcunov]

At this moment (parsing of options on startup) we're
hardly if ever get problem with strdup. Still to be
consistent with the rest of the program code do

 - use xstrdup, to print error message if we failed
 - emergency exit from program on error
