server: Use a high precision timespec directly for poll timeouts on supported platforms.

Instead of first converting to milliseconds, then back to a nanosecond-precision
timespec.

This mitigates a side effect of the global current_time and monotonic_time
being updated on every server call's timeout, where the end time of any unrelated
server call is moved into the future (depending on the frequency of server calls).

By using a more granular timeout, the overall frequency of server calls doesn't have
as great of an effect on each individual timeout, as we don't have to wait for an
entire millisecond (which was due to the ceiling operation in get_next_timeout).

server: Use epoll_pwait2 for the main loop on Linux.

This allows higher precision waits, to match the other platforms where
we can already use a timespec directly.
