[PATCH] trace2: correct trace2 field name documentation

[Josh Steadmon <steadmon@google.com>]

Correct the api-trace2 documentation, which lists "signal" as an
expected field for the signal event type, but which actually outputs
"signo" as the field name.

This patch has been split off from the "Add a JSON Schema for trace2
events" series. The documentation discrepancy was discovered in the
process of testing the schema validation in that series.
