Steffen Eiden cbcab61c65 libpv: fix dependency checking
Fixes a bug that make still tried to build libpv even when the
compilation of libpv was turned off.
This lead to a build bug when one of the dependencies was not met.

Also fixes the check of the OpenSSL version at build time.i

Fixes: 38639269 ("libpv: New library for PV tools")
