app-admin/sudo: add USE=system-digest & USE=libressl
Add system-digest USE flag for building with support of using message
digest functions from libgcrypt, LibreSSL or OpenSSL, depending on
USE gcrypt or libressl, instead of sudo's own implementation.
Minor amend of USE flag descriptions as per descriptions from sudo's
configure.ac and ChangeLog.
