gdbstub: let the debugger resume from guest panicked state

Browse Source 
While in general we forbid a "continue" from the guest panicked
state, it makes sense to have an exception for that when continuing
in the debugger.  Perhaps the guest entered that state due to a bug,
for example, and we want to continue no matter what.
