Update community/vault to 1.4.1

I made a stab at this here:

https://gitlab.alpinelinux.org/tsarna/aports/-/tree/tsarna-vault-1.4.1

It builds but I haven't tested yet. I had to enable CGO to get it to build or else I got the "cannot find runtime/cgo" error mentioned here 96867937 but that fix was later reverted for causing other problems. I don't really understand the implications of CGO and a) whether this is and acceptable workaround or b) there is a better way to deal with the problem.

So, basically I am opening this since I am out of my depth on Go. If the direction I have headed is OK I can test the build and submit an MR, otherwise I'd appreciate advise from the package maintainer, or if they just want to update it themselves that's even better 😄.

Thanks!
