traced_perf sepolicy tweaks
* allow shell to enable/disable the daemon via a sysprop
* don't audit signals, as some denials are expected
* exclude zygote from the profileable set of targets on debug builds.
I've not caught any crashes in practice, but believe there's a
possibility that the zygote forks while holding a non-whitelisted fd
due to the signal handler.
