touch: remove unneeded GETOPT32 defines

Browse Source 
Long options handling (getopt32 vs getopt32long) is done in libbb.h, no need to
care here of the same logic. This cleans the code a bit.

Also, --no-create was grouped as a SUSv3 option, where as the short -c was not.
Even if it is part of SUS, leave it out as was the short option.

v2: Fix for disabled ENABLE_LONG_OPTS. getopt32long does not like
  IF_FEATURE_xxx() style conditionals... :/
