Update module civetweb (bug fixes and increased stack size requirement)

[gudnimg]

Proposal

The current revision in west.yml refers to commit zephyrproject-rtos/civetweb@e6903b8

zephyr/west.yml

Line 41 in f9a0e20

revision: e6903b80c09d17cd1a8bb32e40080005558aad29

As I understand it, Zephyr is directly using this repo: https://github.com/zephyrproject-rtos/civetweb

I was trying to help with an issue related to Civetweb #33516 and noticed the Zephyr version pulled by West is out of date. One commit of interest: zephyrproject-rtos/civetweb@3565451

The stack size increases a lot and may rule out some boards.

Example:

When compiling sample samples/net/civetweb/http_server the stack size increases by 24576 bytes. For a Nucleo F429ZI board this represents an increase of 12.5%.

Command: west build samples/net/civetweb/http_server -b nucleo_f429zi
