CheckSFV: use mktemp instead of tempfile
tempfile(1) is to my knowledge something Debian specific. It has been removed from debianutils >= 5.0 (currently in Debian unstable) following a deprecation warning message added in May 2020: https://salsa.debian.org/debian/debianutils/-/commit/d19f6bb98f8108f7ec259ec31e461526c2a96cec https://salsa.debian.org/debian/debianutils/-/commit/6c7ab57b5723ee68f48a24a0a177b41bc538d9f4
Use the more portable mktemp(1) instead.
