patch to remove epoll_wait timeout

This patch fixes the issue for me. Obviously this is not a correct solution,
but it "fixes" the millisecond granularity issue by removing the timeout
entirely.

The reason why the issue happens is because the ticks timer is updated every
millisecond, but when looking at logs (I've added ERR calls to GetTickCount and
Sleep), this will very often (always?) not coincide with the Sleep(1) (or
SDL_Delay(1)) call dosbox calls in Normal_Loop (dosbox.cpp).

--- snip ---
835352.591:0024:err:sync:GetTickCount out=835352591
835352.591:0024:err:sync:Sleep sleeping for 1 msec
--- snip---
835352.591:0024:err:sync:Sleep slept
835352.591:0024:err:sync:GetTickCount out=835352591
835352.592:0024:err:sync:GetTickCount out=835352592
--- snip ---

After the hack however, it works properly:

--- snip ---
836157.685:0024:err:sync:GetTickCount out=836157685
836157.685:0024:err:sync:Sleep sleeping for 1 msec
--- snip---
836157.686:0024:err:sync:Sleep slept
836157.686:0024:err:sync:GetTickCount out=836157686
--- snip ---
