tracing: remove shutdown-on-signal

This feature cannot be reasonably implemented this way
without inherently being susceptible to race conditions
that lead to hangs, crashes, etc.

What’s more, implementing this for some signals only
(and it can only be implemented for some signals at all)
may lead to the impression that it is a guaranteed
feature, when really consumers of the tracing output
*need* to be able to handle abrupt ends meaningfully.
