Previously "set -e" meant any non-zero exit code from perf stat would
cause a test failure. As a non-zero exit happens when there aren't
sufficient permissions, check for this case and make the exit code
2/skip for it.

Running shellcheck on stat_all_metricgroups.sh reports
below warning:
In ./tests/shell/stat_all_metricgroups.sh line 7:
function ParanoidAndNotRoot()
^-- SC2112: 'function' keyword is non-standard. Delete it.
As per the format, "function" is a non-standard keyword that
can be used to declare functions. Fix this by removing the
"function" keyword from ParanoidAndNotRoot function

Switch the test program to sleep that makes more sense for system wide
events. Only enable system wide when root or not paranoid. This avoids
failures under some testing conditions like ARM cloud.

Uncore events as group leaders fail in per-thread mode causing exit
errors. Enable system-wide for metricgroup testing. This fixes the HPC
metric group when tested on skylakex.

Test every metric and metricgroup with 'true' as a workload. For
metrics, check that we see the metric printed or get unsupported. If the
'true' workload executes too quickly retry with 'perf bench internals
synthesize'.
v3. Fix test condition (thanks to Paul A. Clarke <pc@us.ibm.com>). Add a
fallback case of a larger workload so that we don't ignore "<not
counted>".
v2. Switched the workload to something faster.
