hpc: use System.FilePath.(</>) instead of (++)
Summary:
BAD: "." ++ "/" ++ "/absolute/path" == ".//absolute/path"
GOOD: "." </> "/absolute/path" == "/absolute path"
Also replace `++ ".ext"` with `<.> "ext"`. Although it doesn't fix any
bugs in this instance, it might in some other. As a general rule it's
better not to use (++) on FilePaths.
