tests: remove obsolete uses of "$$" in temporary file names

Those were useful when tests might have been run in the same
directory and in parallel.  Now, each test is run in a newly-
created empty directory.
* tests/cp/backup-1: Remove obsolete uses of "$$".
* tests/cp/same-file: Likewise.
* tests/dd/misc: Likewise.
* tests/mv/part-symlink: Likewise.
* tests/mv/to-symlink: Likewise.
* tests/touch/fail-diag: Likewise.
