[PATCH trace-cmd 1/5] trace-cmd/listen: Remove use of sighandler_t

[Seth Forshee <seth.forshee@canonical.com>]

sighandler_t is a GNU extension and may not be defined if
_GNU_SOURCE is not set. To minimize the potential for build
problems, change signal_setup() to declare its handle argument
the same way struct sigaction declares the sa_handler member.
