Mark pass_sccopy gate and execute functions as final override

It is customary to mark the gate and execute functions of the classes
representing passes as final override but this is missing in
pass_sccopy.  This patch adds it which also silences clang warnings
about it.

	* gimple-ssa-sccopy.cc (class pass_sccopy): Mark member functions
	gate and execute as final override.
