math/ceres-solver: Fix PLIST with glog 0.5.0

- Add BUILD_DEPENDS to ensure glog 0.5.0+
- Bump PORTREVISION for package change

In aac9906, glog changed to cmake and provided
its own cmake module, therefore ceres-solver does not install its glog-detection
cmake module [1].

from CMakeLists.txt [1]:
762 if (GLOG_FOUND AND NOT FOUND_INSTALLED_GLOG_CMAKE_CONFIGURATION)
763   # Version of glog detected was not built with CMake, install our glog module
764   # file to enable detection in CeresConfig.
765   install(FILES "${Ceres_SOURCE_DIR}/cmake/FindGlog.cmake"
766           DESTINATION ${RELATIVE_CMAKECONFIG_INSTALL_DIR})
767 endif()
