configure: test for zlib only w/--enable-experimental

Only builds with --enable-experimental require zlib currently.
A base install of mingw will not include the development headers and
library. libwebp itself will now build in such environments.
Additionally, remove -lz from **/Makefile.am, -lz will be added to LIBS
by AC_CHECK_LIB when necessary.
