cli: Cleanups for tcl argument handling 

* Keep the previous behavior when no tcl script is used
* Do not treat "-" as a flag but as a positional argument
* Keep including <unistd.h> as it's also used for other functions (at
  least for the emscripten build)
* Move the custom getopt implementation into the Yosys namespace to
  avoid potential collisions
