Update libmemcached `config.guess`/`config.sub` to latest

[mattwebbio]

When trying to install this gem on Ubuntu 22.04 on ARM, I'm experiencing the following failure:

checking build system type... config/config.guess: unable to guess system type

This script, last modified 2009-04-27, has failed to recognize
the operating system you are using. It is advised that you
download the most up to date version of the config scripts from

http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD
and
http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD

If the version you run (config/config.guess) is already up to date, please
send the following data and any information you think might be
pertinent to <config-patches@gnu.org> in order to provide the needed
information to handle your system.

config.guess timestamp = 2009-04-27

configure: error: cannot guess build type; you must specify one

Updating the gem's copy of libmemcached with the latest config.guess and config.sub (as suggested in the error) resolved the issue for me. This should close https://github.com/arthurnn/memcached/issues/210 and https://github.com/arthurnn/memcached/issues/161.
