libbpf: Fix missing #pragma in libbpf_utils.c

The recent sha256 patch uses a GCC pragma to suppress compile errors for
a packed struct, but omits a needed pragma (see related link) and thus
still raises errors: (e.g. on GCC 12.3 armhf)

libbpf_utils.c:153:29: error: packed attribute causes inefficient alignment for ‘__val’ [-Werror=attributes]
  153 | struct __packed_u32 { __u32 __val; } __attribute__((packed));
      |                             ^~~~~

Resolve by adding the GCC diagnostic pragma to ignore "-Wattributes".
