procutil: move mainfrozen() to new resourceutil.py
The i18n module practically depends on procutil for mainfrozen() but
since procutil depends on i18n, it would be a circular dependency if
i18n depended directly on procutil. The cycle is currently resolved by
having the higher-level util module calculate the "datapath" and
inject it into i18n. Extracting mainfrozen() to a new module lets us
clean up the dependencies.
