V3: cyclictest: clean up getopt_long() parameters

V3: unchanged from V2

cyclictest getopt_long() parameter clean up.
Clean up before following patch which will add a new option.

  Some elements of long_options were not in alphabetical order.

  Some elements of optstring were not in alphabetical order.

  '-e', '--latency' was missing help text

  short form of --duration ('D') was missing from optstring

  Change a few instances of leading spaces to tabs.

  Add white space to long_options to improve readability.

  Some cases of the switch processing the result of
    getopt_long() were not in alphabetical order.

  Did _not_ clean up option value parsing and processing.
