elog-gen: sort exceptions for file stability
In the elog-gen template there is an iteration over a Python `set`.
Sets are not guaranteed to have any particular order from execution to
execution, which means that a template generated from the exact same
data can have different values. Add a 'sorted' into the set iteration
so that the file output is stable.
Stability is useful for two reasons:
1. Some repositories check in a version of the file for UT
purposes, which causes drastic changes in the version in that
repo.
2. Tools like ccache can only speed up builds if the header files
are unchanged.
