Attached patch adds os.getrandom(): thin wrapper on the Linux getrandom() syscall.

os.getrandom() can return less bytes than requested.

The patch is incomplete: it doesn't include documentation.

I chose to not implement a loop to not loose entropy if a following call fails (ex: fail with EINTR). Rationale:
https://mail.python.org/pipermail/security-sig/2016-July/000072.html

We should also add Solaris support later.

See also #27776: "PEP 524: Make os.urandom() blocking on Linux".
