cmd/go: 'go get' should not delete binaries when run from $GOBIN

When 'go install' is run without arguments in a directory containing a
main package, it deletes an executable file with the same name as the
package (presumably created by 'go build' previously).

'go get' in module mode executes the same code after updating and
downloading modules. However, the special case was misfiring because
we passed an empty list of patterns to InstallPackages.

Fixes #32766
