add default tshark_path for CentOS7

[xueguanwen]

Hi,when i try pcap-analyzer in CentOS7,TSharkNotFoundException occured.

TSharkNotFoundException: TShark not found in the following locations: C:\Program Files\Wireshark\tshark.exe, /usr/bin/tshark, /usr/lib/tshark, /usr/local/bin/tshark Either place tshark there or add more paths to the config file.

the reason is default tshark path "/usr/sbin/tshark" of CentOS7 is not in all your possible_paths.
so why not add it? even though i can add it to config.ini.

def get_tshark_path():
    """
    Finds the path of the tshark executable. If the user has specified a
    location in config.ini it will be used. Otherwise default locations
    will be searched.

    :raises TSharkNotFoundException in case TShark is not found in any location.
    """
    config = get_config()

    if sys.platform.startswith('win'):
        win32_progs = os.environ.get('ProgramFiles(x86)', '')
        win64_progs = os.environ.get('ProgramFiles', '')
        tshark_path = ('Wireshark', 'tshark.exe')
        possible_paths = [config.get('tshark', 'tshark_path'),
                          os.path.join(win32_progs, *tshark_path),
                          os.path.join(win64_progs, *tshark_path)]
    else:

                          '/usr/local/bin/tshark']

    for path in possible_paths:
        if os.path.exists(path):
            return path
    raise TSharkNotFoundException('TShark not found in the following locations: ' + ', '.join(possible_paths) +
