libwebsockets: use native sysroot's ssl config

During the compile step, CMake will attempt to generate a test
certificate with openssl-native using a hard-coded path to the openssl
config:

	openssl req -config /etc/ssl/openssl.cnf ...

Thus using the build host's openssl config. If the build host's openssl
is configured with options that openssl-native does not understand or
accept, the test certificate will not be generated:

[log.do_configure on openSUSE 16.0]

	OpenSSL executable: .../build/tmp/work/cortexa53-crypto-oe-linux/libwebsockets/4.5.2/recipe-sysroot-native/usr/bin/openssl
	 GENCERTS = 1
	Generating SSL Certificates for the test-server...

	CMake Warning at lib/tls/CMakeLists.txt:528 (message):
	  !!! Failed to generate SSL certificate for Test Server!!!:

	  OpenSSL return code = 1

and the subsequent do_install() step will fail:

	| CMake Error at test-apps/cmake_install.cmake:126 (file):
	|   file INSTALL cannot find
	|   ".../build/tmp/work/cortexa53-crypto-oe-linux/libwebsockets/4.5.2/build/libwebsockets-test-server.key.pem":
	|   No such file or directory.

	ERROR: Task (.../layers/meta-openembedded/meta-oe/recipes-connectivity/libwebsockets/libwebsockets_4.5.2.bb:do_install) failed with exit code '1'

Fix the location where CMake looks for the openssl.cnf file in order
to use the one that comes with the openssl-native that will be used to
generate the certificate. Thus ensuring that they are in step in terms
of which configuration options will be acceptable.
