Android's libc creates a signal stack for every thread it creates. In Go, minitSignalStack picks up this existing signal stack and puts it in m.gsignal.stack. However, if we later try to exit a thread (because a locked goroutine is exiting), we'll attempt to stackfree this libc-allocated signal stack and panic. Fix this by clearing gsignal.stack when we unminitSignals in such a situation. This should fix the Android build, which is currently broken.
