    meson: Fix failure to detect bsd_auth.h presence
    
    bsd_auth.h file needs to be included after 'sys/types.h', as documented in
    https://man.openbsd.org/authenticate.3
    
    The reason a similar looking stanza works for autoconf is that autoconf
    automatically adds AC_INCLUDES_DEFAULT, which in turn includes sys/types.h.
    
    Backpatch to all versions with meson support.
