lint: Force amd64 ARCH for Windows golangci-lint runs

Trying to run `make cross-lint` on a M1 mac results in:
% GOOS=windows /Users/teuf/dev/crc/tools/bin/golangci-lint run

WARN [runner] Can't run linter goanalysis_metalinter: buildir: failed to load package w32uiautomation: could not load export data: no export data for "github.com/openstandia/w32uiautomation"
ERRO Running error: 1 error occurred:
	* can't run linter goanalysis_metalinter: buildir: failed to load package w32uiautomation: could not load export data: no export data for "github.com/openstandia/w32uiautomation"

Not exactly clear what's happening, but Windows on arm64 is not a
thing, and forcing GOARCH to amd64 avoids this issue, so this commit
does that.
