archive documentation: attributes are taken from the tree by default

By default, git-archive takes attributes from the tree being archived.
People however often wonder why their attempts to affect the way how the
command archives their tree by changing .gitattributes in their work tree
fail.

Add a bit of explanatory note to tell them how to achieve what they want
to do.

Note that attributes are by default taken from the `.gitattributes` files
in the tree that is being archived. If you want to tweak the way the
output is generated after the fact (e.g. you committed without adding an
appropriate export-ignore in its `.gitattributes`), adjust the checked out
`.gitattributes` file as necessary and use `--work-tree-attributes`
option. Alternatively you can keep necessary attributes that should apply
while archiving any tree in your `$GIT_DIR/info/attributes` file.
