[LEDE-DEV] [PATCH] scripts: fix build warning when overriding packages

[Zefir Kurtisi]

If core packages are overridden, CONFIG_OVERRIDE_PKGS is set
based on the scan order of packages, which eventually causes
that config value to be modified on each build and with
that causes the build process to warn for configuration
being out of sync.

This commit changes the CONFIG_OVERRIDE_PKGS to be sorted
and prevents that false warning.
