Bug#783232: release-notes: two comments about the security section

[Romain Francoise <rfrancoise@debian.org>]

Package: release-notes
Severity: normal

As mentioned on IRC, I reviewed the security section of the "What's new
in Debian 8" chapter and:
- it mentions the protected_symlinks feature of the kernel as new, but
  afaik it was already enabled in wheezy
- it advertises hardening-wrapper, but it's planned for deprecation or
  removal in stretch

Thanks,
