fix up btrace options & manpage
PATCH 1/1 fix up btrace options & manpage
The btrace script & man page didn't quite match for options, and the btrace script was missing a few options in the getopts specification (b&n). Also, there seems to be no such thing as a "summarize" option anywhere, so remove it.

(this goes after the general manpage cleanup I sent, sorry, should have been a series in retrospect)
