For reproducers it is useful to encode the notion of the current working directory in the VFS mapping. This enables us to handle relative files transparently, as long as the current working directory doesn't change over time.

This change is motivated by a current bug in LLDB's reproducers. When a relative path to a binary is passed to the debugger, we fail to resolve it during reproducer replay, because the resolved (absolute) path doesn't match any entry in the VFS.
