Add license argument to genrule
We implement the license argument to maven_jar by producing a
prebuilt_jar package that includes the license file as a dependency.
However, we can't depend on all artifacts that we ever download being
jars, so this doesn't work. Instead, just let a genrule provide a
license directly, adding it as a dep of the genrule. Of course,
genrules can't have deps, so we have to hack them into the command to
get buck to pick them up.
