Daniel Swarbrick 3fb5f70b0c Drop redundant GOOS build tags if already in filename
Drop redundant GOOS build tags at start of file if the constraint is
already specified by the filename, e.g. foo_GOOS.go or
foo_GOOS_GOARCH.go, avoiding potential confusion in future.

cf. https://pkg.go.dev/cmd/go#hdr-Build_constraints
