Add = to PARSE_BOARD regex to make it less greedy.

For instance in the Sparkfun 1.6 core, we have:

  promicro16.build.vid.0=0x1B4F
  promicro16.build.vid.1=0x1B4F
  promicro16.build.vid=0x1B4F

So we end up matching all 3 instead of just the last one.

Adding the = means we're looking for promicro16.build.vid= so
not catching the .0 or .1 version.
