Fix zlib library name

[pema99]

The name of the zlib library in the zip files you are hosting (when using feature prebuilt) is "zlibstatic", not just "z". Without this fix, the following causes linker errors:

• Clone repo
• cargo build -F prebuilt

hey man, I had to revert your change since made the linux build fail.
But that was my fault since the runner was not working properly.
It should be fixed now.
Would you mind to send yet another PR? maybe a only on windows statement will be needed...
not sure =)

@jkvargas I checked all 3 platform's zip files. Seems it's needed on all 3 - it's call zlibstatic on all



(these are all the dylib distributions)
