btrbk: Prefix PATH instead of resetting it. 

Some distros (notably NixOS) don't even use /usr/bin, /sbin, etc.
Instead, they use PATH to specify which programs are available to a
given executable.

This patch changes the behavior or `btrbk` so it extends PATH with its
own search paths instead of resetting it. This allows users and distros
to specify their own custom location for `btrfs` via `PATH`.
