Alberto Bertogli 14e270b7f5 test: Replace uses of which with command -v
The `which` command isn't guaranteed to be available, it is just
extremely common; `command -v` is the standard way to do find an
executable program. See https://lwn.net/Articles/874049/ for more
details.

This patch replaces the uses of `which` with `command -v`, which only
appears in a couple of tests.
