Ignore generated files under crypto/ from crypto/.gitignore

In /crypto/.gitignore, list files that are generated by a build done
under /crypto/. In the outer /.gitignore, list files under /crypto/
only if they are created by the export process.

This commit slightly refines both lists and adds some build products
to /crypto/.gitignore.
