[PATCH 3/4] perf tests task_analyzer: check perf build for libtraceevent support

[Aditya Gupta]

Currently we depend on output of 'perf record -e "sched:sched_switch"', to
check whether perf was built with libtraceevent support.

Instead, a more straightforward approach can be to check the build options,
using 'perf build --has libtraceevent', to check for libtraceevent support.
