merge: teach -Xours/-Xtheirs to symbolic link merge

Browse Source 
The -Xours/-Xtheirs merge options were originally defined as a way
to "force" the resolution of 3way textual merge conflicts to take
one side without using your editor, hence did not even trigger in
situations where you would normally not get the <<< === >>> conflict
markers.

This was improved for binary files back in 2012 with a944af1d
("merge: teach -Xours/-Xtheirs to binary ll-merge driver",
2012-09-08).

Teach a similar trick to the codepath that deals with merging two
conflicting changes to symbolic links.
