[Buildroot] [git commit] package/dhcp: fix build with zlib

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=789a08dac5808401629d6fc586b7377f54ebb316
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

internal bind is in version 9.11 and so doesn't support pkg-config
like bind 9.16 resulting in the following build failure since commit
0c8dd6ebd656e06cf99a63eb93343715f4853503:

configure: error: include/zlib.h not found.
