uloop: handle waker pipe write() return value
Recent glibc warns if result of read() or write() is unused.
Added a retry in case of EINTR, all other faults are silently discarded.

-----
- I was not able to reproduce the EINTR case, but it seems to be the right
thing to do
- Retrying on EAGAIN in this case would be weird as there is no one to read
from the other end of the pipe. We could call waker_consume() directly but
since the size of the message is just one byte, I think this would be dead
