Don't write VFS2 gofer client timestamps back on dentry destruction.
This feature is too expensive for runsc, even with setattrclunk, because fsgofer.localFile.SetAttr() ends up needing to call reopenProcFD(), incurring two string allocations for the FD pathname, an fd.FD allocation, and two calls to runtime.SetFinalizer() when the fd.FD is created and closed respectively (b/133767962) (plus the actual cost of the syscalls, which is negligible).
