setproctitle: avoid __attribute__((constructor)) when using gcov

I really hate supporting this hack, especially since the issue
is fixed for newer gcc/gcov users.  However, many systems are on
older gcc and it takes a while for folks to upgrade, so it'd be
nice to encourage more coverage testing.

This isn't needed for newer gcov + gcc in Debian testing/unstable,
but gcov/gcc 4.4.5-8 on Debian squeeze fails to pass argc/argv/envp
to ((constructor)) functions when using gcov.

We'll drop this hack when support for Debian squeeze is terminated
(probably 2014-2015).
