    vos: Remove pthread send/receive select()
    
    Commit 65e701fee4968b17066bb81e25b7adaa4024d4f3 introduced a couple of
    select() calls when the pthreaded vos writes to or reads from a usd
    pipe, corresponding to the IOMGR_Select() calls in LWP. However, these
    select() calls are unnecessary, since the read() or write() calls
    themselves will block anyway. The reason they are there for LWP is so
    the IOMGR can run another process while we're waiting for the file
    descriptor to be ready.
    
    The select() in ReceiveFile currently incorrectly waits for the output
    to be ready for reading, even though we're trying to write to it. As a
    result, if we try to 'vos dump' to a pipe with the pthreaded vos (such
    as stdout), we will hang forever, since it will never be ready for
    reading.
    
    To fix this, just get rid of the select() calls, since they don't
    really do anything.
