kria.pb.object.get: Fix two typos in method names

Apparently, the methods are named .setNotfoundOk and .setDeletedvclock:
less capitalisation. Without this, trying to set the :not-found-ok or
:deleted-vclock properties would result in an IllegalArgumentException.

Found with lein eastwood.

kria.pb.content: Fix setting the :charset

When a Content object has a :charset, the code failed in two ways: it
tried to use .setCharSet instead of .setCharset, and even tried to use
it on the ByteString, instead of the builder object.

This patch corrects both mistakes. Found via lein eastwood.
