nix: stop downloading POMs for Clojure dependencies
Clojure dependencies require only JARs to work. Downloading POMs is both
a waste of time, space, and bandwidth. In addition POMs create edge
cases that we would have to handle, an would rather avoid.

For example, the `guice` package which shows up in the classpath
includes a JAR named `guice-4.2.2-no_aop.jar`. The issue with that is
that there is no corresponding POM in the directory:
https://repo1.maven.org/maven2/com/google/inject/guice/4.2.2/

Either we have to make a special case for such packages, or we can just
skip POMs entirely and avoid the mess.
