  debugging: slides: mention older addr2line lack of symbol+offset notation

This notation is a recent binutils addition (2.39, August 2022) and Ubuntu
22.04 does not have it (has 2.38). Clearly document the versions supporting
it and mention the faddr2line script to obtain the same effect with older
binutils.

Also split the "Kernel oops debugging" in 2 slides (addr2line and
decode_stacktraces.sh) to fit the new content.
