[PATCH 08/10] build: Add missing includes in configure check for OpenSSL

[Guillem Jover]

When compiling with the -Werror=implicit-function-declaration build flag
which will be the default with upcoming gcc and clang compilers for the
modern-C transition, the configure check for OpenSSL fails due to a
missing include for exit(3).
