The wrong conditional check for newly allocated memory would make the
function to fail when the allocation was successful and access invalid
memory when the allocation failed.

Commit c306a693f3 ("buffer: Use size_t for argc argument in
ssh_buffer_(un)pack()") mentioned unpack in the commit log, but it only
touches the pack variants. Extend the conversion to unpack.
Pre-initialize the p pointer to avoid possible use before
initialization in case of early argc check failure.
This fixes build failure:

I noticed that there was no example showing server side public key encryption in the examples
so I added this one. I used authorizedkeys as a global to minimize the changes to the original
code as well as I was not sure the correct methodology of determining the .ssh directory location
for a user not using Linux. One code using the user parameter to determine the location to use
instead if desired.
