lib: fix tests for 386 platforms

Browse source 
Tests in lib/structure_helpers_test.go pass on amd64 platforms but fail
on 386 platforms. This can be reproduced with the following steps:

1. Create a Dockerfile in aerc's source folder:

	FROM i386/alpine:edge

	RUN apk update && apk upgrade
	RUN apk add --no-cache go make scdoc

	WORKDIR aerc

	COPY . .

	RUN make

	CMD make tests

2. Build the image:
	$ docker buildx build --platform=linux/386 -t test .

3. Run the image:
	$ docker run --rm --platform=linux/386 -it test

The test in lib/structure_helpers_test.go will fail.

If the same above steps are done with this patch applied, all tests pass.
