    Mk/Uses/go.mk: Do not insist on always pulling go.mod and distfile from GOPROXY
    
    Some Go packages are not listed on pkg.go.dev (usually because their
    versioning scheme does not satisfy Go requirements) and, as a
    consequence, are not accessible through proxy.golang.org.
    
    Instead of resorting to hacks with pseudo-versions and/or enumerating
    dependencies manually with modules2tuple, support fetching go.mod and
    distfile from the usual places using DISTFILES mechanism. This will
    allow bypassing GOPROXY for go.mod and the distribution archive, but
    will still use it for fetching dependencies (with GO_MODULE).
