kodi, mpd: fix samba4 related dependency mistakes

This commit fixes the following kconfig warning:

   warning: (BR2_PACKAGE_KODI_LIBSMBCLIENT && BR2_PACKAGE_MPD_LIBSMBCLIENT) selects BR2_PACKAGE_SAMBA4 which has unmet direct dependencies (!BR2_PACKAGE_SAMBA && BR2_USE_MMU && BR2_USE_WCHAR && BR2_TOOLCHAIN_HAS_NATIVE_RPC && BR2_TOOLCHAIN_HAS_THREADS && !BR2_STATIC_LIBS && !BR2_nios2)

by updating the kodi and mpd Config.in files to properly take into
account the dependencies of the BR2_PACKAGE_SAMBA4 option that they
select.
