    Add important paths to the sandbox
    
    The web process needs to be able to load internal Epiphany libraries,
    which are stored in pkglibdir. These will normally be under /lib or
    /lib64 and therefore already whitelisted by WebKit, but not if we're
    using a custom build prefix, e.g. if Epiphany is built in JHBuild and
    WebKit is not.
    
    Similarly, in DEVELOPER_MODE where we load from the builddir, we want to
    be able to access the builddir.
