Johannes Sixt 889c6f0e4d tests: use test_ln_s_add to remove SYMLINKS prerequisite (trivial cases)
There are many instances where the treatment of symbolic links in the
object model and the algorithms are tested, but where it is not
necessary to actually have a symbolic link in the worktree. Make
adjustments to the tests and remove the SYMLINKS prerequisite when
appropriate in trivial cases, where "trivial" means:

- merely a replacement of 'ln -s a b && git add b' by test_ln_s_add
  is needed;

- a test for symbolic link on the file system can be split off (and
  remains protected by SYMLINKS);

- existing code is equivalent to test_ln_s_add.

test_description='git checkout-index test.
This test registers the following filesystem structure in the cache:
path0/file0 - a file in a directory
path1/file1 - a file in a directory
and attempts to check it out when the work tree has:
path0/file0 - a file in a directory
path1 - a symlink pointing at "path0"
Checkout cache should fail to extract path1/file1 because the leading
path path1 is occupied by a non-directory. With "-f" it should remove
the symlink path1 and create directory path1 and file path1/file1.
