Test development version of libuv in CI

Recently, a broken version of libuv was released breaking BIND on
several platforms. The offending commit [1] was on the development
branch for months, but we didn't notice.

In nightly pipelines, build the current 'main' (actually 'v1.x') branch
of libuv and run the unit and system tests against it.
