Fix off-by-one when checking that clocksel is valid index to the array.

Also fix a compiler warning:

src/cyclictest/cyclictest.c: In function 'process_options':
src/cyclictest/cyclictest.c:1828:31: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  if (clocksel < 0 || clocksel > ARRAY_SIZE(clocksources))
