[aur-general] Remove packages salome-multipr and salome-visu

[Michele Mocciola]

Please, remove
- salome-multipr (https://aur.archlinux.org/packages/salome-multipr/)

- salome-visu (https://aur.archlinux.org/packages/salome-visu/)

These modules are obsolete (see http://git.salome-platform.org/gitweb/) and are not compatible with the other modules of salome available on AUR.
Cheers,

Michele Mocciola
