[PATCH 2/2] winedbg: only check for break/watch points on first chance exceptions

Previously it was checked if a break / watchpoint triggered even on second chance exceptions
(but breakpoints are always handled on first chance)
this could produce problems in following situation

1 byte instruction (breakpoint placed here)

when the int3 raises a second chance exception eip points at the int3 itself,
but is decreased by 1 in context fixup of winedbg (break_adjust_pc)
then it is checked if a breakpoint is hit, which will lead winedbg to think it broke on the breakpoint just before int3
this fixes the problem by only checking for break/watch points on first chance exceptions
