`command -v' is shell builtin required by POSIX [1] and supported on all
common shells (bash, zsh, dash, busybox sh, mksh). `which' utility is not
presented on some containers (e.g. Fedora, openSUSE), also going to be
removed from future Debian versions.
Also remove stderr redirection to /dev/null as it's unnecessary when
using 'command': POSIX says "no output shall be written" if the command
isn't found.
