proc/native/linuc: Better native.Process.stop performance (#1874) 
* proc/native/linux: only set breakpoints on threads that receive SIGTRAP

* proc/native/linux: do not call (*Thread).Stopped inside (*Process).stop

(*Thread).Stopped is slow because it needs to open, read and parse a
file in /proc, we don't actually need to do that, we can just rely on
the value of Thread.os.running.

Benchmark before:

BenchmarkConditionalBreakpoints-4              1        12476166303 ns/op

Benchmark after:

BenchmarkConditionalBreakpoints-4   	       1	10403533675 ns/op

Conditional breakpoint evaluation: 1.24ms -> 1ms

Updates #1549
