RFR [XS]: 8224958: add os::dll_load calls to event log

[Thomas Stüfe]

Hi Matthias,

this is useful. Can you please

- add the dlerror output to the log (where easily available)
- I see an existing issue on some platforms where the return value of
dlerror() is copied without null check first. dlerror() may return NULL.
Can you please add null checks where needed?

Thanks!

..Thomas
