Appending it with version number which is compile time constant.

We don't need to parse for default value of event source, it is only
for case when user gives some specific name to event_source in
postgresql.conf and it that case, we expect that user provides the
same name during register command of event source, some thing
like:
regsvr32 /n /i: PostgreSQL_HEAD <install_dir_path>\lib\pgevent32.dll

Here point to note is that pgevent.dll never does any parsing or lookup
for event source name, either user provides it or we use default value.
