    Eliminate sim_client include of getopt.h
    
    Commit 9139a60c94c24e41109574e84e7cda9c2dc3fb38 added an unconditional
    include of getopt.h, which is non-portable (it isn't present on HP-UX)
    and unecessary for getopt().  The same commit also disabled the
    include of unistd.h (which is necessary for getopt()), as sim_client
    no longer indirectly includes autoconf.  Make the unistd.h include
    unconditional and remove the getopt.h include.
