If privileges for scapy were dropped, but username remain unchanged, path.exist() would trigger an exception. Fix that by moving whole if statement under try-except. Fixes secdev#4618

Brief description
It seems that #4571 haven't fixed all the cases. One that is not handled - when scapy process don't have permissions to open the folder (e.x. script that calls scapy drops permissions and therefore home folder is no longer accessible).
In that case
path.existswill throw an exception and scapy will crash.Correct fix is to put
if not path.exists()into sametry-exceptblock.Scapy version
2.6.1
Python version
3.12
Operating system
Linux 6.12
