	tool/runruby.rb: remove LD_PRELOAD-like env-var options from
	 runruby.rb

	LD_PRELOAD sometimes forces loading libraries into unrelated
	executables. For example, macOS on recent Apple Silicon can execute
	arm64 and arm64e binaries by default, and /usr/bin/clang is built as
	arm64e. If Ruby is built as arm64, and mkmf launched through runruby.rb
	spawns /usr/bin/clang, dynamic loader tries to load libruby (arm64e)
	into clang (arm64). This force-load causes library load failure.
	In theory, we don't need both LD_PRELOAD and LD_LIBRARY_PATH at the same
	time, because executables requiring libruby already have libruby
	dependency, so LD_LIBRARY_PATH is enough for this case.
