EPOLLRDHUP seems to be an additional define being used in libtirpc code.
This commit adds this define to bsd emulator.
We will need to implement the corresponding event in bsd emulator.

libntirpc developers should be mindful of adding corresponding defines in bsd
emulator code everytime we use/introduce linux specific code.
