[PATCH] package_*.bbclass: Ensure OVERRIDES doesn't change sstate signature

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Changes to OVERRIDES (e.g. from changing MACHINE) should not change
the sstate signatures of do_package_write_*. Exclude the variable
explicitly in the package classes to avoid this.
