    Don't include readline headers from tracepoint.c
    
    I was curious why updating readline caused so much to be to rebuilt,
    so I look at all the uses of the readline headers.  Most are included
    for valid reasons (either readline directory or for tilde_expand); but
    the includes in tracepoint.c didn't seem to be used.
    
    This patch removes them.  Tested by rebuilding.
