py3: fix curses chunkselector fallback (when diffs are too large) on py3

Authored by spectral on Jan 16 2020, 3:20 PM.



Previously we showed the message using Exception.message, which is removed in
py3. Since crecordmod.fallbackerror inherits from error.Abort, we can just use
b'%s' % exception to print the message. This does not print the hint, but
that's fine - we don't set one. We inherit from error.Abort so that if a
codepath doesn't handle fallback specially, it exits to the terminal with a sane
message instead of an unknown exception error.
