Buck: Simplify build rules
Buck: Simplify build rules

Since [1] dependencies to targets used in $(location //path/to:target)
macro are added implicitly.

This can be verified by using Bucks audit and targets commands:

  $ buck targets --json api
  [...]
  "buck.type" : "genrule",
  "name" : "api",
  "deps" : [ ],
  [...]

So explicit dependencies are empty, but implicit dependencies are still
present:

  $ buck audit dependencies api
  //gerrit-extension-api:extension-api
  //gerrit-extension-api:extension-api-javadoc
  //gerrit-extension-api:extension-api-src
  //gerrit-plugin-api:plugin-api
  //gerrit-plugin-api:plugin-api-javadoc
  //gerrit-plugin-api:plugin-api-src
  //gerrit-plugin-gwtui:gwtui-api
  //gerrit-plugin-gwtui:gwtui-api-javadoc
  //gerrit-plugin-gwtui:gwtui-api-src
