interpret source language "en" as "POSIX" (more precisely: "none specified")

we set it to that value when writing xliff, as the header is mandatory
and no better value is possible. it seems unlikely that an unqualified
"english" would be used if somebody meant to actually specify a source
language, so this hack should be ok.
