pyanaconda: payload: split rsync command for /boot/efi to handle FAT …

…filesystem limitations

The previous rsync command attempted to preserve attributes (permissions, ownership, symlinks)
that are not supported by FAT. This commit splits the rsync process for `/boot/efi` to avoid
these incompatible options and ensure proper handling of FAT-specific filesystems.

Resolves: rhbz#2329379
