openntpd: add optional dependency on LibreSSL

Browse Source 
OpenNTPD looks for a crypto library with tls_config_set_ca_mem, which
is available in LibreSSL but not OpenSSL. If tls_config_set_ca_mem is
found, crypto support is added to the build.

Because this is not currently checked, crypto support might not be
added due to the order of the build. Add a small check to see if
BR2_PACKAGE_LIBRESSL is selected, and if so, add a dependency for it.

Also add a note about this in the Config.in help section.

redistributing the local clock. It just works.
Crypto support is available if the LibreSSL library is
enabled.
