cmd: update vendored golang.org/x/mod

Pull in CL 500335. It teaches modfile.IsDirectoryPath to recognize all
relative paths that begin with a "." or ".." path element as a valid
directory path (rather than a module path). This allows removing the
path == "." check that CL 389298 added to modload.ToDirectoryPath.

go get golang.org/x/mod@6e58e47c  # CL 500335
go mod tidy
go mod vendor

Updates #51448.
Fixes #60572.
