meson: Add prefix=/usr/local/pgsql to default_options

autoconf set PREFIX to /usr/local/pgsql, so using the same default for meson
makes sense. The effect on windows is that installation defaults to installing
to C:/usr/local/pgsql rather than meson's default of C:/, which doesn't seem
perfect, but OK enough.
