BUG/MINOR: systemd: always restore signals before execve()

Since signals are inherited, we must restore them before calling execve()
and intercept them again after a failed execve(). In order to cleanly deal
with the SIGUSR2/SIGHUP loops where we re-exec the wrapper, we ignore these
two signals during a re-exec, and restore them to defaults when spawning
haproxy.

This should be backported to 1.6 and 1.5.
