Subject: perf tools: Add 'signed' flag setting back into trace-event-parse.c

Commit 13999e59343b042b0807be2df6ae5895d29782a0 (perf tools:
Handle the case with and without the "signed" trace field)
removed code to set the FIELD_IS_SIGNED flag that was originally
added by commit 26a50744b21fff65bd754874072857bee8967f4d
(tracing/events: Add 'signed' field to format files).

This adds it back.
