[dia/fix-i18n] meson.build: set dialocaledir with a prefix

    meson.build: set dialocaledir with a prefix
    
    localedir's value is 'share/locale'. If a prefix is not given,
    Dia will search for the locale files in the build path instead
    of in the given prefix, resulting in an English interface as
    the locale files are not found.
    
    Fixes #427
