contrib/xpycscope.el is out of date (fix enclosed)

[jlschenck]

After updating emacs, I found that xpycscope.el no longer works because of an elisp function that no longer works. I found a simple fix, replacing two lines (2010, 2142):

(process-kill-without-query xxxx)

is replaced with

(set-process-query-on-exit-flag xxxx nil)

Thanks,
Jeff
