meson.build: define PATH_MAX where it's missing PATH_MAX is not POSIX and can be missing on some systems, notably Windows (which provides MAX_PATH instead tough) and Hurd. Let's define it to a sane value where missing, i.e. the one it's defined to in limits.h. Except on Windows where we're limited to 260.
