CL 250437 removed the zsysnum_darwin_*.go files containing the SYS_*
contants for macOS. This was done assuming that users should migrate
away from direct syscalls to libSystem wrappers. Let's not force users
of this package on when they want to do that and re-add the
zsysnum_darwin_*.go files and mark the consts as deprecated.
We can still remove these once macOS actively prevents use of direct
syscalls.

On some platforms (namely Linux), Select and Pselect update the
passed-in timeval/timespec, which might lead to failing tests in
case of an EINTR. Fix this by always resetting the timeval/timespec
before calling Select/Pselect.
Also change accept timeouts within 2/3 margin of the expected timeout,
like already done in TestSelect. While at it, fix the failure log to use
the common "got X, expected Y" message.
