  [OpenMP][libomp] Fix /dev/shm pollution after forked child process terminates

Made library registration conditional and skip it in the __kmp_atfork_child
handler, postponed it till middle initialization in the child.
This fixes the problem of applications those use e.g. popen/pclose
which terminate the forked child process.
