1. Rename Servo build dependency sls files …

   This change groups the various sls files that set up the Servo build
   environment into a single folder to:
    - make their purpose more clear in the top.sls file
    - make it easier to add auxiliary files (i.e. map.jinja)
   
   Also, don't install the Servo build dependencies on the Buildbot master,
   but make sure to keep git installed to update the Salt file tree.

4. Make Android states more robust to version updates …

   Use separate directories for separate versions of the
   SDK, NDK, and toolchain, and use symlinks to point to the current
   versions. This is more robust for a few reasons:
    - Partially-completed upgrades to new versions won't touch
      existing versions on the disk
    - The symlinks aren't updated until the respective new version is
      completely installed, allowing for more transactional updates.
    - The symlinks also allow for constant paths in the bash_profile file
      and the buildbot config, which means less moving parts to break.
      In particular, the relevant buildbot config is on the master, and
      using symlinks makes it unnecessary to use Salt orchestration to
      gate changes to the master buildbot config on changes on the cross
      builders.
   
   Ideally, these states would also use file.directory with clean: True
   to clean out old versions of the SDK, NDK, and toolchain, but I wasn't
   able to get this working properly yet (the just-downloaded files would
   keep getting cleaned away).
   
   This also eliminates our use of cmd.wait, which was recently put on the
   deprecation path in Salt, and replaces it with cmd.run + creates: True.

5. Remove .bash_profile setup …

   The buildbot configuration already sets the correct environment
   variables for Android builds, so it's unnecessary to set them via
   .bash_profile.

6. Drop to the warning log level for Travis …

   archive.extracted is fairly loud because each extracted file is listed
   both in INFO log level output and the highstate summary.
   This gets around exceeding Travis's 4MB log length limit.
