[PATCH v2 1/2] tests/: Do not use `sed -i`

[cgit at cryptocrack.de (Lukas Fleischer)]

"-i" isn't part of the POSIX standard and doesn't work on several
platforms such as OpenBSD. Use a temporary file instead.

Signed-off-by: Lukas Fleischer <cgit at cryptocrack.de>
---
Now uses a temporary file in order not to lose the exit status of
cgit_url.
