turn hidden --trace into a NOP

The --trace has helped in early stages analyze Podman code.  However,
it's contributing to dependency and binary bloat.  The standard go
tooling can also help in profiling, so let's turn `--trace` into a NOP.

[NO TESTS NEEDED]

-	//    span.LogKV(key1, val1, key2, val2, key3, val3, ...)
-	//
-	// The keys must all be strings. The values may be strings, numeric types,

-	// system), and with it some powerful costs: use this feature with care.
-	//
-	// IMPORTANT NOTE #1: SetBaggageItem() will only propagate baggage items to
-	// *future* causal descendants of the associated Span.
-	//
-	// IMPORTANT NOTE #2: Use this thoughtfully and with care. Every key and
