[Buildroot] [git commit] erlang: always use Buildroot's zlib

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ec5378038f80f444ce7f5106283c7cccb8faae16
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

While Erlang includes a version of zlib, it's intended for Windows and
there's an expectation that non-Windows platforms provide it. It's also
not as regularly updated as the one in Buildroot. This change makes
Erlang always use a Buildroot-provided zlib.

Fixes this compile error:
