[Qemu-trivial] [PATCH] qemu-common: Add definition for O_NONBLOCK

[Stefan Weil]

backends/rng-random.c which was added by commit
5c74521d249486fa3e749dbbf6d56a70d4d7235f needs
macro O_NONBLOCK.

The macro O_NONBLOCK is not defined for all hosts.
Adding a default definition fixes builds for MinGW.

This is a build fix. Therefore I'd appreciate if it could be
committed soon.

Thanks
Stefan W.
