NetBSD ptrace interface does not populate watchpoints to newly-created threads. Solve this via copying the watchpoints from the current thread when new thread is reported via TRAP_LWP. Add a test that verifies that when the user does not have permissions to set watchpoints on NetBSD, the 'watchpoint set' errors out gracefully and thread monitoring does not crash on being unable to copy watchpoints to new threads.
