Prefer MESONINTROSPECT env var to find mesonintrospect if set

This is new in meson 0.40. Makes sure we find and use the
mesonintrospect from the same location as our meson, and
not some other meson version that just happens to be in the
path. We might be using meson directly from a checkout, for
example.
