option.sh: don't bother checking for GNU tar

Browse source 
releases aren't reproducible anyway. we were
using options available in gnu tar for this.

it will be revisited at a later date. however, the next
time this is done, we will use another method because
there are in fact portable ways to create tarballs
reproducibly, documented on reproducible-builds.org

to be revisited, at a later date. for now, remove bloat.
