package/oracle-mysql: don't use bundled zlib

As spotted by Thomas Petazzoni during review of
https://patchwork.ozlabs.org/project/buildroot/patch/20200713215943.2240412-1-fontaine.fabrice@gmail.com,
oracle-mysql uses its bundled version of zlib if it is not found on the
system

So explictly disable zlib if needed and add a patch fixing build
failures without it
