 mportselect: always delete existing symlinks

 If the previously selected port was uninstalled, the 'current' symlink
 would be left pointing to the old select file that is no longer
 available.

 The condition using 'file exists' follows the symlink and checks its
 target, not the symlink itself. It is safe to always call 'file delete'
 as deletion of a non-existing target is not an error.
