FindGLEW: Fix CMAKE_FIND_LIBRARY_SUFFIXES content
FindGLEW.cmake
temporarily changes the content of CMAKE_FIND_LIBRARY_SUFFIXES
to look for static and dynamic GLEW library. However, it wasn't storing and restoring the initial content of the variable causing issues in user project.
This PR fixes this issue.
Topic-rename: FindGLEW-lib-suffixes
