saip: rework file sizes for "half-defined" template files
Define the file size early if possible.
Some templates (e.g. for 5GS) define files which aren't completely defined.
Fixes the parsing for 5GS SUCI_Calc_Info which doesn't have a file size defined.
The saip-tool will other crash when reading a 5G enabled profile:
```
