[syslog-ng] [PATCH] Fix compilation without OpenSSL.

[Gergely Nagy]

While most places where OpenSSL was used were guarded by ENABLE_SSL
ifs, some were not. This patch adds those guards to lib/crypto.c,
modules/afsql/afsql.c and tests/loggen/loggen.c.

It also makes sure that OPENSSL_LIBS gets emptied when enable_ssl is
set to no.

 dnl Right now, openssl is never linked statically as it is only used by the
 dnl TLS build of the afsocket plugin which is loaded dynamically anyway.
