Run executables from PATH instead of /usr/bin

Browse Source 
Not all distributions install non-system binaries into /usr/bin. For
example, NixOS installs packages to /nix/store using a unique hash
generated from the inputs used to build it:

/nix/store/jld7jh3ilvbg91zvn1bdyawfc55b9jk8-polkit-0.118-bin/bin/pkexec
