Only check for RAPL filtering if we use the rapl provider

[ribalba]

Currently we always check if rapl filtering is active

def check_energy_filtering():
    if platform.system() != 'Linux':
        print(TerminalColors.WARNING, '>>>> RAPL could not be checked as not running on Linux platform <<<<', TerminalColors.ENDC)
        return True

    result = subprocess.run(['sudo', 'python3', '-m', 'lib.hardware_info_root', '--read-rapl-energy-filtering'],
                            stdout=subprocess.PIPE,
                            stderr=subprocess.PIPE,
                            cwd=os.path.abspath(os.path.join(CURRENT_DIR, '..')),
                            check=True, encoding='UTF-8')
    return "1" != result.stdout.strip()

We should only do this if we are actually going to use the rapl metrics provider. As this is an ERROR check it will fail running GMT even if you are not using RAPL

Ya, totally. I would argue it makes the most sense to move it to the reporters.
