Remove legacy dependency detection macros.

- Before the new CMake buildsystem in 1.8, Ceres used non-standard
  HINTS variables for dependencies.  For backwards compatibility CMake
  macros were added to translate these legacy variables into the new
  (standard) variables.
- As it has now been multiple releases since the legacy variables
  were used and they no longer appear in any of the documentation
  support for them has now expired.
