scripts: maps: Cleaned up/moved header generation before rendering
Should've probably been two commits, but: 1. Cleaned up tracebd.py's header generation to be consistent with dbgbmap.py and other scripts. Percentage fields are now consistently floats in all scripts, allowing user-specified precision when punescaping. 2. Moved header generation up to where we still have the disk open (in dbgbmap[d3].py), to avoid issues with lazy Lfs attrs trying to access the disk after it's been closed. Found while testing with --title='cksum %(cksum)08x'. Lfs tries to validate the gcksum last minute and things break.
