bsdtar, tar: remove tar alternative

Alternative for tar was introduced to make switch from gnu tar to bsdtar in base-devel easier.

However, bsdtar has different interface than gnu tar, and with alternatives using gnu tar as tar is actually harder when it is needed.

There are also many user-used scripts assuming gnu tar, which are broken now. They should not be affected because of internal matters of packaging.
