This patch fixes the init scripts helper functions file to
filter out the hat/child process separator as currently used
by the parser, '//' rather than what used to be used, the '^'
symbol. This fixes bugs where profiles that covered regexs (e.g.
'/usr/lib/firefox-4.0.1/firefox{,*[^s][^h]}') and thus were being
improperly filtered away and unloaded when reloading apparmor policy.
