lib/smbconf: add a python function for raising smbconf exceptions

The previous implementation in C was private to the module. Add
a small python wrapper function so that a different python module
may reuse the implementation.

The python level function is prefixed with "_" to mark it as
"private". Only future cooperating modules in the samba sources
should make use of it.

The function is shared at the python level as per the recommendation:
