[pkg-lighttpd] Bug#654151: Please enabled hardened build flags

[Moritz Muehlenhoff]

Package: lighttpd
Version: 1.4.30-1
Severity: important

Please enabled hardened build flags

Please enable hardened build flags for your package. Since your
package has already been converted to dh, setting debian/compat
to 9 is all you need to do.

I've tested in a local build that this is sufficient to enable
hardened build flags.

Cheers,
