Subject: tracing: Pull up calls to trace_define_common_fields()

Call trace_define_common_fields() in event_create_dir() only.
This avoids trace events to handle it from their define_fields
callbacks and shrinks the kernel code size:

   text    data     bss     dec     hex filename
5346802 1961864 7103260 14411926         dbe896 vmlinux.o.old
5345151 1961864 7103260 14410275         dbe223 vmlinux.o
