meson.build: Don't misdetect posix_memalign() on Windows
Currently we incorrectly think that posix_memalign() exists on
Windows. This is because of a combination of:
* the msys2/mingw toolchain/libc claim to have a
__builtin_posix_memalign when there isn't a builtin of that name
* meson will assume that if you have a __builtin_foo that
counts for has_function('foo')
Specifying a specific include file via prefix: causes meson to not
treat builtins as sufficient and actually look for the function
itself; see this meson pull request which added that as the official
way to get the right answer:
https://github.com/mesonbuild/meson/pull/1150
Currently this misdectection doesn't cause problems because we only
use CONFIG_POSIX_MEMALIGN in oslib-posix.c; however that will change
in a following commit.
