This fixes buildifier warnings that were not fixed in automatic
mode:
$ find . \( -name BUILD -o -name "*.bzl" \) -print \
| xargs buildifier --lint=warn
* Remove unused variables
* Pattern `src/test/java/com/google/gerrit/server/project/Util.java`
has no wildcard ('*')
* All calls to rules or macros should pass arguments by keyword
(arg_name=value) syntax
* ctx.new_file is deprecated, used ctx.actions.declare_file instead
