[Buildroot] [PATCH] package/open62541: cleanup tools files after installation

[Scott Fan]

The open62541 tools directory is indeed 52 MiB, which built as a standalone package
named 'libopen62541-1-tools' in launchpad. Nothing is required at runtime.

See the official debian control file template:
https://raw.githubusercontent.com/open62541/open62541/master/debian/control-template

See https://launchpad.net/~open62541-team/+archive/ubuntu/ppa/+packages

libopen62541-1-dev   Open source implementation of OPC UA - development files
libopen62541-1-tools Open source implementation of OPC UA - tools
