testsuite: Add default_packed filters

Fix test cases assumptions that target has alignment constraints.

gcc/testsuite/ChangeLog:

	* gcc.dg/attr-copy-4.c: Unpacked may still have alignment of 1
	on targets with default_packed.
	* gcc.dg/c11-align-9.c: Remove AVR target filter and replace
	with default_packed filter.
