Add the commit identifier to the version printout
Currently it is not possible to identify the exact source code of the development/ non-release builds.
One solution is to include the commit identifier to the version printout for non-release builds.
It would be good to print it in a separate line.
Example:
```
compiler -v
TTCN-3 and ASN.1 Compiler for the TTCN-3 Test Executor
Version: 8.0.0
Build date: Jul 14 2021 09:04:20
Compiled with: GCC 7.5.0
Using OpenSSL 1.1.1 11 Sep 2018
Commit id: 935ba6f596
Copyright (c) 2000-2021 Ericsson Telecom AB
```
Or something similar.
