testsuite: Adjust btf-bitfields-1.c for default_packed

Browse Source 
If target packs structures by default, the bitfield offset which the
test validates must be adjusted to not include padding.

gcc/testsuite/ChangeLog:

	* gcc.dg/debug/btf/btf-bitfields-1.c: Adjust the checked offsets
	for targets which pack structures by default.
