zdump: Disable warnings about unaligned access to packed struct members

Browse Source 
This is a false positive because IBM Z architecture supports unaligned
memory accesses.

dfo_s390.c: In function ‘df_s390_dump_init’:
dfo_s390.c:218:29: warning: taking address of packed member of ‘struct df_s390_hdr’ may result in an unaligned pointer value [-Waddress-of-packed-member]

      |                             ^~~~~~~~
