Remove viral readproc group dependency.

This has been copy pasted and isn't actually required.

Test: all hals manually tested to work on internal marlin (which have them binderized).
  Note: tv hals not tested (and they never have been). Filed b/36562029
  Note: for thermal hal, could only run VTS/check logs for errors.
Test: lshal outputs proper stuff
