S3FS Compatability fixes

Merge request accepted. Basic sanity test passed. Leaving open for review.

Proposed an alternative to @thhafner's change and merged into 1.0,x.

@thhafner can you test this out and report your results here?

@jmdeleon need to use a ternary operator instead of null coalescing as realpath returns a string or FALSE not NULL when it cannot find the file.

I tested with the ternary operator and it works as expected with s3fs. I have not validated it with a standard public filepath yet.

I have a small test environment set up for this, and I believe the standard file system paths have not regressed with this change.
