gdb/arm: Terminate unwinding when LR is 0xffffffff

ARMv7-M Architecture Reference "A2.3.1 Arm core registers" states
that LR is set to 0xffffffff on reset.

ARMv8-M Architecture Reference "B3.3 Registers" states that LR is set
to 0xffffffff on warm reset if Main Extension is implemented,
otherwise the value is unknown.
