[FIX] base: do not restrict xml_id length in IrTranslationImport

Those constraints are an incorrect leftover from 0a42a9de which removed the size constraints on a
number of core tables including 'name' and 'model' of ir_model_data.

Temporary table tmp_ir_translation_import limits columns size (imd_name and imd_model).
Those columns are only used to match columns 'model' and 'name' in ir_model_data.

But in ir_model_data, columns 'model' and 'name' are VARCHAR, no reasons to restrict the temporary table.
