bootstrap, gnulib-tool: correct the translations wget command

Using the -np (--no-parent) option doesn't prevent wget from
traversing the given URL to a default depth of 5, and since
the domain directory contains a href="/latest/" link, this
means that wget searches through all domains anyway and will
also download PO files that are meant for other packages.
When getting the PO files for the nano domain, for example,
you will end up with af.po and ast.po (and many others) too,
but there are no African nor Asturian translations for nano.

So, use the --level option instead, to stop wget from looking
any further than the given URL.

* build-aux/bootstrap (po_download_command_format2): Restrict
recursion to a single level.
* gnulib-tool (func_import): Likewise.
* pygnulib/GLImport.py (GLImport.execute): Likewise.
