refactor(users/glittershark): Rename to grfn r/2485

Rename my //users directory and all places that refer to glittershark to
grfn, including nix references and documentation.

This may require some extra attention inside of gerrit's database after
it lands to allow me to actually push things.

+  cachedir /home/grfn/.cache/tarsnap
+
+  # Tarsnap key file
+  keyfile /home/grfn/.private/tarsnap.key
+

+
+  ### Commonly useful options
+
+  # Use SI prefixes to make numbers printed by --print-stats more readable.

+
+  ### Other options, not applicable to most systems
+
+  # Aggressive network behaviour: Use multiple TCP connections when
+  # writing archives.  Use of this option is recommended only in
+  # cases where TCP congestion control is known to be the limiting
+  # factor in upload performance.

+  # Attempt to reduce tarsnap memory consumption.  This option
+  # will slow down the process of creating archives, but may help
+  # on systems where the average size of files being backed up is
+  # less than 1 MB.
+  #lowmem
+
+  # Try even harder to reduce tarsnap memory consumption.  This can
+  # significantly slow down tarsnap, but reduces its memory usage
+  # by an additional factor of 2 beyond what the lowmem option does.

+  # Snapshot time.  Use this option if you are backing up files
+  # from a filesystem snapshot rather than from a "live" filesystem.
