p7zip is not available on arm/v6

[ttionya]

Rclone 1.59.0 is built on Alpine 3.16, the tool's dependency p7zip cannot be found on the Alpine 3.16 arm/v6 platform.

I have created an issue jinfeihan57/p7zip#187 under the p7zip project and waiting for it to be fixed. In the meantime I will evaluate the possibility of using alternative tools.

See the GitHub Actions log for errors.

Starting with p7zip 17.04, it is built on p7zip's fork jinfeihan57/p7zip, while the previous version (16.02) was built based on p7zip on sourceforge.

But p7zip 17.04 couldn't pass the test on the armhf platform, so the maintainer removed armhf platform support. You can see pipeline at https://gitlab.alpinelinux.org/alpine/aports/-/jobs/767452. And Alpine 3.16 was released after the removal of armhf platform, so it doesn't have the p7zip package.

I could build a separate image for arm/v6 via the specific Dockerfile, but its tag would not be consistent with that of other platforms, so I did not use this method for ease of use.

Now I use multistage build, arm/v6 based on alpine:3.15, and install the rclone package, but it's only version 1.57.0, other platforms are the latest 1.59.0.

This issue will not be closed until p7zip can be used normally on all platforms.

I found a new 7z package in alpine:3.17 called 7zip. it is only available in alpine:3.17.

Now that rclone is built on alpine:3.17, maybe we can replace p7zip with 7zip.
