package/weston: fix unmet dependencies

Properly propagate dependencies from freerdp to fix the following unmet
dependencies:

    warning: (BR2_PACKAGE_WESTON_RDP) selects BR2_PACKAGE_FREERDP which has
    unmet direct dependencies (BR2_INSTALL_LIBSTDCPP && BR2_USE_WCHAR &&
    !BR2_STATIC_LIBS && BR2_TOOLCHAIN_HAS_THREADS && BR2_USE_MMU &&
    BR2_TOOLCHAIN_HAS_SYNC_4)

Reorder deps to have architectures deps first.

Remove "broken" dependency from comment; add missing ones.
