Corrected inability to build on systems using libressl instead of
openssl (e. g. void linux) by adjusting the #defines in
modules/openssl/stream_peer_openssl.cpp and
modules/openssl/stream_peer_openssl.h to check if
LIBRESSL_VERSION_NUMBER is defined (as done similarly in the following
patch in freebsd:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219362 ).
