cmake: Remove check_link_map.py

This script is looking for a hyperspecific error (mismatched padding
when linking into two simultaneous output sections) that bit us once,
in an era where the linker scripts were less unified.  We haven't seen
it crop up since, and multiple platforms have changed the way they do
this anyway.

It's needless complexity.  Junk it.
