Fix namespace build of zlib gzguts.h on macOS 

Move ABC_NAMESPACE_HEADER_START (and the abc_global.h include) before the
non-LFS prototype block so the bare gzFile references in gzopen64/gzseek64/
gztell64/gzoffset64 resolve to the namespaced type. Without this, building
with ABC_USE_NAMESPACE=xxx fails on platforms that compile this block (e.g.
macOS, which does not define _LARGEFILE64_SOURCE):

  gzguts.h: error: unknown type name 'gzFile'; did you mean 'xxx::gzFile'?

Restores the header ordering used in the previous zlib 1.2.5 sources.
