perf test: Check output of the probe ... --funcs command
Test "perf probe of function from different CU" only checks if the perf
command has failed and doesn't test the --funcs output. In the issue
reported in the previous commit, the garbage output of the --funcs
command was being ignored by the test when it could have been caught.
The script first makes use of --funcs option with the perf probe command
to check if the function "foo" exists in the testfile before adding a
probe to it in the next command. The output of probe...--funcs command
is redirected to stdout, therefore, add '| grep "foo"' to validate the
result.
