[PATCH] replace 'which' with POSIX equivalent 'command -v'

Nah, nothing of the sort. I was just going through the source code of password-store and thought that using `which` was unnecessary and can be replaced with `command -v` without making any significant changes. I'm also in the process of writing my own password store extensions and scripts as a learning experience so sending a patch here was part of the process as well.

I am in favour of incorporating this patch, LGTM.

Just curious: what motivated you to make this change? Did your try to run pass in an environment without `which`, or did `which` exit with an erroneous success status for you?
