Subject: [PATCH] Use find_package(GSSAPI) instead including the module

When including it, CMAKE_DISABLE_FIND_PACKAGE doesn't have the desired
effect. This can cause a CMake error when building mariadb:

"CMake Error at libmariadb/plugins/auth/CMakeLists.txt:123 (SET_TARGET_PROPERTIES):
  SET_TARGET_PROPERTIES Can not find target to add properties to:
  auth_gssapi_client"
