Profiling for perf tests
Stack profiling is quite useful and Linux ZFS test suite does not
current collect that data.
Linux perf is a common tool for this purpose though the perf record
data file can be quite large. With this change, Linux ZFS perf tests
capture perf record data if perf is installed on the system and
PERF_DO_PROFILING environment variable is set.
