c21485d427 mcctrl: include linux/cred.h 
The headers defines __task_cred and other macroes we use, and always
existed; we must have gotten it indirectly on older kernels, it doesn't
hurt to always include

06dd71a7e0 Revert "procfs: add '/proc/pid/stat' to mckernel side and fix its comm" 
This reverts commit b70d470e20.

That commit had been landed too fast after a mistake during migration
from old to new gerrit that didn't keep -1 vote ; it needs some fix

on linux side

ecc850dfef procfs/do_fork: wait until procfs entries are registered 
Do not return from fork() until mcctrl side has created mckernel's
procfs entries for the child PID.

This fixes programs doing fork() immediately followed by opening
/proc/<child pid>/something, and would get some error
