testsuite: Skip cases for default_packed targets

The memchr test cases expect padding to be present in structures.  But
this is not true for targets which pack by default.  Skip these test
cases in order to avoid static assert errors when checking field offsets.

gcc/testsuite/ChangeLog:

	* gcc.dg/memchr.c: Skip for default_packed targets.
	* gcc.dg/memcmp-3.c: Ditto.
