[PATCH] travis: Update to job matrix

[Geoff Levand]

 o Set language to bash (same as generic), so just the
   scrip steps run.
 o Move build-builder to 'before_script'.
 o Switch to a job matrix of 'os' entries with names.

Hi Sam,

This updates the travis file to use a job matrix.  The jobs run should
be unchanged, but this gives the jobs a name, which is displayed in the
travis UI.  A job matrix allows for more advanced logic that we can take
advantage of if we start adding more jobs. 

Please consider.
