bug: Use normal relative pointers in 'struct bug_entry'
With CONFIG_GENERIC_BUG_RELATIVE_POINTERS, the addr/file relative
pointers are calculated weirdly: based on the beginning of the bug_entry
struct address, rather than their respective pointer addresses.
Make the relative pointers less surprising to both humans and tools by
calculating them the normal way.
