bind: avoid build impurity by explicitly enabling/disabling features

The BIND configure script finds extra dependencies in /usr/include and /usr/lib,
and activates additional features if it does. This may cause the build to fail
on systems that cannot use a chroot environment. Actively disabling those
additional features prevents this issue from occurring.
