ftrace_format_##call() and ftrace_define_fields_##call() are
inconsistent at signs of fields.
After reviewed codes, ftrace_format_##call() is correct,
so we change ftrace_define_fields_##call().

tracing: Fix sign fields in ftrace_define_fields_##call()
Add is_signed_type() call to trace_define_field() in ftrace macros.
The code previously just passed in 0 (false), disregarding whether
or not the field was actually a signed type.
