Restore errno in signal handlers. There was a problem where errno could be set in a signal handler and cause bugs if other system calls were interrupted. There isn't strong evidence this is causing any issues, but add this proactively. Bug: 31448909 Test: Ran the backtrace unit tests, backtraces few random processes, Test: forced the ANR path for some zygote based processes. Test: Ran the art ThreadStress test a few times.
