  Fix standalone compilation on Mac
  
  Apple Clang 8.1 doesn't allow implicit conversion from gl::Error to
  egl::Error with the egl::Error::Error(gl::Error&&) constructor. Same
  thing for gl and egl reversed. This commits add conversion constructors
  taking errors by value. There should be not performance impact for
  non-error code paths.
