perf tools: Improve aux_output not supported error
For example:
Before:
$ perf record -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -- ls -l
Error:
branch-loads: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat'
After:
$ perf record -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -- ls -l
Error:
branch-loads: PMU Hardware doesn't support 'aux_output' feature
