Arnaldo Carvalho de Melo b988971662 tools lib subcmd: Make it an error to pass a signed value to OPTION_UINTEGER
Options marked OPTION_UINTEGER or OPTION_U64 clearly indicates that an
unsigned value is expected, so just error out when a negative value is
passed, instead of returning something undesired to the tool.

E.g.:

  # perf bench futex hash -t -4
  # Running 'futex/hash' benchmark:
   Error: switch `t' expects an unsigned numerical value
   Usage: perf bench futex hash <options>

      -t, --threads <n>     Specify amount of threads
