action: expand shell variables before execvp()

Browse source 
Expanding shell variables, including tilde, enables the following type
of keybind:

<keyboard>
    <keybind key="XF86AudioMute">
      <action name="Execute">
        <command>bash ~/mute-script.sh</command>
      </action>
    </keybind>
</keyboard>
