Don't link dirrectly against openssl

All our crypto code is handled by qt nodaways.
No need to carry this dependency.

Especially since it causes warnings on system where there are
twp openssl version installed:
/usr/bin/ld: warning: libcrypto.so.1.0.0, needed by /usr/lib/libQt5Network.so.5.9.0, may conflict with libcrypto.so.1.1
