zlib: remove LDFLAGS workaround.
Added in 4d39b701666370b53a7167c00702a1d7a4213a87 without explanation as
to why.

We also revbump to rebuild the binary. On x86_64-musl, old libz.so,
built with gcc 7, is using a 2132KB RE mmap when dynamically linked,
probably because of a 0x200000 alignment required for the RE section.
After rebuilding, 96KB are used, with the actual RE mmap reduced to 56K.
The new alignment is 0x1000.

<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.

<!-- 
#### Does it build and run successfully? 
(Please choose at least one native build and, if supported, at least one cross build. More are better.)
- [ ] I built this PR locally for my native architecture, (ARCH-LIBC)
- [ ] I built this PR locally for these architectures (if supported. mark crossbuilds):
  - [ ] aarch64-musl
  - [ ] armv7l
  - [ ] armv6l-musl
