* automated/tramp-tests.el (tramp--test-enabled): Move connection

cleanup into this function.  Remove respective code from all test cases.

Handle other errors as well.

link of directories.
(tramp-test22-file-times): Skip if `set-file-times' returns nil.
(tramp-test26-process-file, tramp-test28-shell-command): Let-bind
`kill-buffer-query-functions' to nil.
