Mark BIO_s_log(3) as intentionally undocumented.

Ben Laurie invented the system logging BIO in 1999 and yet,
nothing whatsoever uses it according to codesearch.debian.net.
Besides, it is poorly designed and a crypto library is absolutely
not the place for putting a clumsy system logging facility.
Not everything needs to be a BIO!
