[LTP] [PATCH v1] Fix: dirtyc0w_shmem child process exit with error due to uninitialized lib_pid

[Li Wang]

Hi All,

I have just pushed Wei's patch with a refined description to
make it get rid of the failure before the May release.

NOTE: I'm almost done with the new refactoring work on IPC
and will send out patches after my testing.
