use.desc: Correct/clarify SSL/TLS-related flags

Correct the description of SSL/TLS-related flags to match their modern
use. USE=ssl is a feature flag that enables support for SSL/TLS,
while USE=gnutls and USE=libressl are implementation toggling flags.

Unify the descriptions a bit. Make sure to mention both SSL and TLS
to avoid confusion. Inform about the necessity of enabling USE=ssl
in both implementation flags, and replace 'might' with 'if present'.
