Make lsof 10x faster by caching /proc/net socket info.
I deliberately didn't do this first time round because for me our lsof is already 10x faster than traditional lsof, and caching means we potentially give less information about a socket that's created while we're running. It turns out that traditional lsof caches anyway, so I guess nobody cares. This also fixes a mistake where lsof used CFG_FREE instead of CFG_TOYBOX_FREE.
