Rather than maintain a hardcoded search path for looking up tools and override the user's PATH env setting, respect whatever the user has. This matches the convention of just about every other tool out there. It might break on systems that don't have /sbin in their PATH and they try to run /sbin/mkfs directly, but so be it.
