Change subject: BuildSystem: Remove unused variables.
......................................................................

BuildSystem: Remove unused variables.

Because of a copy-and-paste from the script build_tools/download_externals,
the script build_tools/list_valid_installed_externals got its local variables.
However in the latter, three variables were not used actually.
