[PATCH for-9.0 v2 5/7] qtest/virtio-9p-test.c: consolidate create symlink tests

[Daniel Henrique Barboza]

fs_unlinkat_symlink() does the same thing as fs_symlink_file() while
also removing the created symlink. We also want every test to not leave
stuff behind after each run to avoid subsequential runs to fail.

We can achieve all that by:

- remove fs_unlinkat_symlink(). fs_unlinkat_symlink() is now named
  fs_create_unlinkat_symlink();

- remove 'real_file' and the created dir at the end of
  fs_create_unlinkat_symlink().

The hardlink tests dir names were updated because now we have one less
test.
