[Buildroot] [PATCH v1] package/icu: disable icu config

[Thomas Devoogdt]

From: Thomas Devoogdt <thomas.devoogdt at barco.com>

Seen while using BR2_PER_PACKAGE_DIRECTORIES, not sure on how to reproduce.

Fixes:

/usr/bin/install: cannot stat 'config/icu-config.1': No such file or directory

There was a proposal in the past to do exactly the same:

https://lore.kernel.org/buildroot/20230516173411.823978-1-bernd.kuhls@t-online.de/

The icu-config script was deprecated upstream:
