perf script: Fix error when printing 'weight' field
In SPE traces the 'weight' field can't be printed in 'perf script'
because the 'dummy:u' event doesn't have the WEIGHT attribute set.
Use evsel__do_check_stype(..) to check this field, as it's done with
other fields such as "phys_addr".
Before:
$ perf record -e arm_spe_0// -- sleep 1
$ perf script -F event,ip,weight
Samples for 'dummy:u' event do not have WEIGHT attribute set. Cannot print 'weight' field.
After:
$ perf script -F event,ip,weight
