Andreas Kling c3351d4b9f Kernel: Make VirtualFileSystem functions take credentials as input
Instead of getting credentials from Process::current(), we now require
that they be provided as input to the various VFS functions.

This ensures that an atomic set of credentials is used throughout an
entire VFS operation.
