not-cancel.h: update common version and make sure we use this one

Update file (same as in NPTL).
Disable unused parts, the remaining inlines will be fixed later.
Copy it to include to be sure that we use this one independently of
chosen threads.

Provide write,close and waitpid_not_cancel for LT new.
Use wait4 syscall instead of waitpid syscall (kernel says so).
Provide open_not_cancel and close_not_cancel for librt's spawn.
