desktuils/tine20: Simplify port to remove unnecessary targets

Both post-extract and post-install targets aren't necessary.
In particular the shifting to get the src to extract into the default
WRKSRC was not only unnecessary, the home-rolled extraction could break
in the future, so just clean the whole thing up.  Verified on Redports.
