[PATCH 2/2] openflow: update libopenflow.m4 to use openssl instead of libssl

[Saul Wold <sgw@linux.intel.com>]

openssl provides both the libssl and libcrypto APIs for linkage, the 1.0.2 of
OpenSSL removed libcrypto from the libssl.pc

+OpenSSL 1.0.2 removed -lcrypto from the libssl.pc, but the openssl.pc
