ANDROID: fix up struct sk_buf ABI breakage

In commit 6c2de0ef ("UPSTREAM: io_uring/af_unix: defer registered
files gc to io_uring release"), a new field is added to struct sk_buf.
We need that new field to resolve real problems, so move it to the
padded area that we had reserved for these types of issues.

Update the .xml file to handle the change in fields for the padding
structure, which is an abi-safe change:

type 'struct sk_buff' changed
  member 'union { struct { __u8 scm_io_uring; __u8 android_kabi_reserved1_padding1; __u16 android_kabi_reserved1_padding2; __u32 android_kabi_reserved1_padding3; }; struct { u64 android_kabi_reserved1; }; union { }; }' was added
  member 'u64 android_kabi_reserved1' was removed
