ui/knotty.py: Fix signal handling of SIGWINCH in BBProgress
Add the ability to pass default signal handler for SIGWINCH in BBProgress
because with multiple instace of BBProgress the original signal handler
set by TerminalFilter (sigwinch_handle) is lost.
This is a fix for stack trace due to multiple async calls of ProgressBar
_handle_resize (ioctl to terminal fd), see:
NOTE: Executing SetScene Tasks
Fatal Python error: Cannot recover from stack overflow.
