    plugins: Work-around srcdir != builddir for Vala
    
    The vala automake rules "cd" into the srcdir to generate its C files,
    completely ignoring the fact that the relative paths it's passed as
    arguments won't be valid after that directory change.
    
    Work-around it by using the absolute paths in the --girdir argument
    instead.
