smartctl_exporter AUR package does not set GOPATH variable correctly

The smartctl_exporter package sets a custom GOPATH location in the prepare() section of the PKGBUILD here on line 23 but then does not set the variable again in the build section. This causes the system to use the default GOPATH location, which does not match the one created in the prepare section.

Because of this the build fails:

copying the same line to the build section causes the package to build and install correctly using makepkg -si. I'd be happy to fix the package (if this isn't a PEBCAK issue) but I have no idea how to even begin doing that.

Re: smartctl_exporter AUR package does not set GOPATH variable correctly

The current PKGBUILD works for me in a clean chroot. What if you try `makepkg` directly or `pkgctl build` from devtools? You could also try a PKGBUILD that is closer to the Go package guidelines.
