packager: TransformCache: include UID + do not use base64 

Summary:
Two things in there:

* Using `base64` was kinda broken, as it can contain slashes, invalid in file names. It would still work however because it would just create a second level folder when doing `mkdirp`. Still I think it's better to fix that correctness.
* Include the UID in the hash, so that different users have different folders for sure, and that we reduce potiential permissions issues. `tmpdir()` already returns a folder that's user-specific on OS X, but this is not a guarantee on all platforms.
