[oe] [meta-oe] [PATCH] libmodbus: add documentation PACKAGECONFIG

[liu.ming50 at gmail.com]

From: Ming Liu <liu.ming50 at gmail.com>

asciidoc, xmlto programs are being checked to decide if documentation
should be generated or not depending on if they are present, this will
definitely lead to a non-deterministic build.

Fix it by adding documentation to PACKAGECONFIG.
