scripts: treemap.py/codemap.py: Use parts of name for char defaults

Browse Source 
So by default, instead of just using "." for tiles, we use interesting
parts of the tile's name:

- For treemap.py, we use the first character of the last by-field (so
  "lfs.c,lfsr_file_write,1234" -> "1").

- For codemap.py, we use the first character of the non-subsystem part
  of the function name (so "lfsr_file_write" -> "w").

This nice thing about this, is the resulting treemap is somewhat
understandable even without colors:

  $ ./scripts/codemap.py lfs.o lfs_util.o lfs.ci lfs_util.ci -W60 -H8

Ok, so maybe the word "somewhat" is doing a lot of heavy lifting...
