[PATCH 13/21] schema: nwfiter: Allow leading/trailing whitespace in 'variable-name-type'

[Peter Krempa <pkrempa@xxxxxxxxxx>]

The reference string parser tolerates some leading/trailing whitespace
for the reference strings as witnessed by
tests/nwfilterxml2xmlin/iter-test3.xml

Allow them in the schema so that the test passes schema validation.
