Build camera related goldfish HALs as brilloemulator for Brillo

Brillo runs a reduced subset of the graphics stack and a different
system configuration from goldfish.  However, many of these HALs still
make sense for Brillo.  Build the HALs with a board name that will allow
the camera and graphics subsystems to pick them up.

Bug: 26936651
Test: brilloemulator is able to pick up and use these HALs to take
      fake pictures.
