          gdb: use -1 for breakpoint::task default value
    
    Failed to take account of an earlier commit:

          gdb: show task number in describe_other_breakpoints
    
    That both of these are my own commits is only more embarrassing.
    
    This small fix updates describe_other_breakpoints to take account of
    the default task number now being -1.  This fixes regressions in
    gdb.base/break.exp, gdb.base/break-always.exp, and many other tests.
