loader: actually stat something that has some chance of existing. (v2)

FindModuleInSubdir seems to expect a / at the end of the subdir its
finding for, so we add the / early, the stat will fail if its
not a subdir, I'm leaving the S_ISDIR in just in case there is another
reason it could return 0. This does look a bit silly in strace
but it seems to work fine.

I have a very intermittent issue where drivers loses its / that
I've been seeing on/off for a while, this may or may not fix it.
