Remove default_pager_paging_file RPC from default pager

The default_pager_paging_storage RPC has already it more than 20 years
ago. Given that we want to change the type of default_pager_filename_t
to use c_string, we can just remove the unused RPC.

Tested that swapon/swapoff still work with the new binaries.
