Address some minor lints

A mildly interesting one is the call to test_wchar2utf8 with a non-null
pointer ("u1"/"dst") but 0 length. In this case we relied on malloc(0)
returning non-null which is not guaranteed.

	src/fish_tests.cpp:1619:23: warning: Call to 'malloc' has an allocation
	size of 0 bytes [clang-analyzer-optin.portability.UnixAPI]
	        mem = (char *)malloc(dlen);
	                      ^
	test_wchar2utf8(w1, sizeof(w1) / sizeof(*w1), u1, 0, 0, 0,
			"invalid params, dst is not NULL");
