Stefan Hajnoczi b33b890cd0 trace: avoid SystemTap dtrace(1) warnings on empty files 
target/hppa/trace-events only contains disabled events, resulting in a
trace-dtrace.dtrace file that says "provider qemu {}".  SystemTap's
dtrace(1) tool prints a warning when processing this input file.

This patch avoids the error by emitting an empty file instead of
"provider qemu {}" when there are no enabled trace events.

Fixes: 23c3d569f4 ("target/hppa: add TLB trace events")
