[PATCH v2 20/30] patman: Convert testBasic() to use an interator

[Simon Glass]

On balance it is easier to use an iterator here, particularly if we need
to insert lines due to new functionality. The only niggle is the need to
keep the previous iterator value around in one case.

Convert this test to use iter().
