Remove compilerplugins/clang/test/cppunitassertequals.hxx

...which isn't needed anymore to suppress warnings from other plugins like
loplugin:external ever since 45c06838e9 "only
unit-test one loplugin at a time".  Also, the declaration of the function test
in cppunitassertequals.hxx had already started to deviate from its definition in
cppunitassertequals.cxx.
