Fix pthread's empth_select() not to change the timeout

Browse source 
Commit 08b94556 introduced the timeout parameter.  The empthread
implementation could change it, at least on some systems, and its user
worked around a possible change.  However, that behavior was not
documented, and it's inconvenient.  Fix the pthread implementation,
and remove the workaround.
