Linux: optimize clone3 internal usage azanella/posix_spawn-clone3
Now that clone3 is used on more architectures, add an optimization
to avoid calling when glibc detects that it is no supported by the
kernel.  It also adds __ASSUME_CLONE3, which allows skip this
optimization and issue clone3 syscall directly.

It does not handle the the small window between 5.3 and 5.5 for
posix_spawn (CLONE_CLEAR_SIGHAND was added in 5.5).

Checked on x86_64-linux-gnu.
