Remove duplicates from clang_devteam_warnings

Since the clang_devteam_warnings are appended to the gcc_devteam_warnings
when strict-warnings are requested, any items present in both the gcc
and clang variables will be duplicated in the cflags used for clang builds.
Remove the extra copy from the clang-specific flags in favor of the
gcc_devteam_warnings that are used for all strict-warnings builds.
