In 'perf test', a return value 2 represents that the test case was
skipped. Fix this value for perftool_testsuite test cases to
differentiate between skip and pass values.

summary information
Currently print_overall_results prints the number of fails in the
summary, example from base_probe tests in testsuite_probe:
## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY ::
11 failures found
test_invalid_options contains multiple tests and out of that 11 failed.
Sometimes it could happen that it is due to missing dependency in the
build or environment dependency.
Example, perf probe -L requires DWARF enabled. otherwise
it fails as below:
./perf probe -L
Error: switch `L' is not available because NO_DWARF=1
"-L" is tested as one of the option in:
for opt in '-a' '-d' '-L' '-V'; do
<<perf probe test>>
print_results $PERF_EXIT_CODE $CHECK_EXIT_CODE "missing argument
for $opt"
Here -a and -d doesn't require DWARF. Similarly there are few other
tests requiring DWARF.
To hint the user that missing DWARF could be one issue, update
print_overall_results to print a comment string along with summary
hinting the possible cause. Update test_invalid_options.sh and
test_line_semantics.sh to pass the info about DWARF requirement since
these tests failed when perf is built without DWARF.
Use the check for presence of DWARF with "perf check feature" and append
the hint message based on the result.
With the change:
## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY ::
11 failures found :: Some of the tests need DWARF to run

As a form of validation, it is a common practice to check the outputs
of commands whether they contain expected patterns or match a certain
regular expression.
This output checking helper is designed to allow checking stderr output
of perf commands for unexpected messages, while ignoring messages that
are known to be harmless, e.g.:
"Lowering default frequency rate to \d+\."
"\d+ out of order events recorded."
etc.

Shellcheck is becoming a standard when building perf to prevent
any unnecessary mistakes. Fix shellcheck warnings in perf testsuite.

As a form of validation, it is a common practice to check the outputs
of commands whether they contain expected patterns or match a certain
regex.
Add helpers for verifying that all regexes are found in the output, that
all lines match any pattern from a set and that a certain expression is
not present in the output.
In verbose mode these helpers log mismatches for easier failure
investigation.
