[PATCH util-modular 4/4] build.sh: add initial support for meson

[Peter Hutterer]

When we don't find autogen.sh but we do find meson.build, swap the configure
and make commands over for meson and ninja.

Some things aren't feature-equivalent yet:
- distcheck doesn't exist for ninja but it's hooked up as if it did
- a custom make command doesn't work for ninja
