Revert "package/swupdate: add patch to fix build issue with some toolchains"

This patch caused an unfortunate regression that prevents any handlers
from being registered (runtime issue). This means swupdate cannot
perform any update. Upstream has reverted it.

This reverts commit a8cc6eeec5a665db5689083312beef14a9afbafa.
