    Fixes to meson build to match the former autotools build
    
    - conf: Set PACKAGE_STRING (used in gcab --version) correctly.
    - conf: Set LOCALEDIR to the absolute path.
    - manpage: Use PACKAGE_STRING (which is already quoted).
    - introspection: Set package name to 'libgcab-1.0'.
    - introspection: Add missing GLib-2.0 include.
