Add Chmod() method to File 
`os.File` offers a `Chmod()` method. This is often safer and more direct
to use than `os.Chmod()` because it operates on an open file descriptor
rather than having to lookup the file by name. Without this, it's
possible for the target file to be renamed, in which case an
`os.Chmod()` would either fail or apply to any file that's taken its
place.

Therefore, add the `Chmod()` method to the `File` interface, and
implement it for all `File` implementations. The bulk of this change is
in `MemMapFs`, which required moving the chmod functionality down into
the `mem` package so that it can be shared between both `mem.File` and
`MemMapFs`.

Anish Athalye b598fbbf55 Improve handling of mode bits 
- "/" should have mode `os.ModeDir|0755`, not `0000`. Among other
  things, this had resulted in `mode.IsDir()` returning false for root
  prior to this patch.
- `Mkdir`, `MkdirAll`, and `OpenFile` shouldn't be allowed to set
  permissions that are otherwise illegal through `Chmod`. This mirrors
  what Go's `os` package does: it calls `syscallMode(mode)`, which
  effectively clears out the same bits that are disallowed by `Chmod`.
- `MkdirAll` should use the given permissions for all intermediate
  directories that are created, not just for the final directory. Prior
  to this patch, intermediate directories were created with mode bits
  `0000`. Besides the permission bits being wrong, `mode.IsDir()` would
  return false for these directories prior to this patch.

Alex Tomlins a269144fd6 Fix MemMapFs.Remove() to really delete the file. 
It was attempting to delete a file with a hardcoded path of "name" as
opposed to the path in the `name` variable.

Fixing this exposed a deadlock because the function was attempting to
acquire an exclusive lock when it already had a read lock.
