Description:
------------
A change in error text (initial capitalization) for the socket extensions makes a test fail in PHP 8.

The issue was introduced here: https://github.com/php/php-src/commit/7ff8eaa5451275a5ce97b29381fc08412e6489d7

The test is ext/sockets/tests/socket_set_option_bindtodevice.phpt

Test script:
---------------
#!/bin/sh
# Run on the ubuntu:20.04 docker image:
#   docker run --rm --privileged -v $(pwd):/work -w /work ubuntu:20.04 /work/repro.sh
set -ex
DEBIAN_FRONTEND=nointeractive
apt-get update
apt-get install -y --no-install-recommends autoconf bison \

./buildconf -f
./configure --disable-all --disable-phpdbg --enable-posix --enable-sockets --without-libxml --without-sqlite3 --without-pdo-sqlite
make -j $(nproc)
make test TESTS=ext/sockets/tests/socket_set_option_bindtodevice.phpt
