[oe] [PATCH] libgpiod: fix packaging of tools

[Martin Hundebøll]

The default packaging adds files from ${bindir} to the primary package,
so that following packages don't see any files in ${bindir}. This causes
the libgpiod-tools package to empty, as it is appended (+=) to PACKAGES.

Change the assignment to PACKAGES to a prepend (=+) to populate the
libgpiod-tools package with the gpio{detect,find,get,info,mon,set}
executables.

To avoid missing tools for existing installations of libgpiod, the
libgpiod-tools package is setup as a recommendation by libgpiod when the
tools package config is enabled.
