Subject[PATCH] perf script: Always allow field 'data_src' for auxtrace
If use command 'perf script -F,+data_src' to dump memory samples with
Arm SPE trace data, it reports error:

# perf script -F,+data_src
Samples for 'dummy:u' event do not have DATA_SRC attribute set. Cannot print 'data_src' field.

This is because the 'dummy:u' event is absent DATA_SRC bit in its sample
type, so if a file contains AUX area tracing data then always allow
field 'data_src' to be selected as an option for perf script.

Fixes: e55ed3423c1b ("perf arm-spe: Synthesize memory event")
