scripts: Adopted self-parsing script for dgbflags/err.py encoding
This has just proven much easier to tweak in dbgtag.py, so adopting the same self-parsing pattern in dbgflags.py/dbgerr.py. This makes editing easier by (1) not needing to worry about parens/quotes/commas, and (2) allowing for non-python expressions, such as the mode flags in dbgflags.py. The only concern is script startup may be slightly slower, but we really don't care.
