[OE-core] [PATCH] dpkg, opkg, rpm-postinsts: avoid repackaging when changing IMAGE_FEATURES

[Paul Eggleton]

Recipes cannot depend on the value of IMAGE_FEATURES; in this case the
result is do_package task signatures changing every time IMAGE_FEATURES
changes, causing a large number of task re-executions. The
implementation of the log capturing really needs to be changed to
capture these in a different place and possibly not even conditional
upon IMAGE_FEATURES at all, but this will be invasive at this point in
the development cycle. For now, remove the variable dependencies to fix
the immediate problem.

Fixes [YOCTO #4246].
