perf test: Fix record test on KVM guests

perf test: Fix record test on KVM guests

Using precise flag with br_inst_retired.near_call causes the test fail
on KVM guests, even when the guests have PMU forwarding enabled and the
event itself is supported.

Remove the precise flag in order to make the test work on KVM guests.
