fix(csv_as_enclosure_json): files do not match

See issue [#10](adamtornhill/maat-scripts#10)

On macOS, cloc saves file paths with leading "./" while
code-maat leaves this prefix out.

As a consequence all weights are set to 0.0 because
the normalized_weight_for(module_name) never finds
a match.

The bugfix removes a leading "./" prefix, if it exists,
when initializing a StructuralElement.

Note: This fix combines the associated bugfix on branch python3
into a single commit.
