teststuite - avoid parts of builtin-has-attribute tests requireing alias support.

2019-01-08  Iain Sandoe  <iain@sandoe.co.uk>

gcc/testsuite/

	* c-c++-common/builtin-has-attribute-3.c: Skip tests requiring symbol
	alias support.
	* c-c++-common/builtin-has-attribute-4.c: Likewise.
	Append match for warning that ‘protected’ attribute is not supported.
