go/importer,os/exec: use testenv.GoToolPath

Browse Source 
These were the last two occurences of exec.Command("go", ...) in all of
std cmd. Checked with:

	gogrep '$(f is(func))("go", $*_)' std cmd

Also changed lp_windows_test to use a test package name to avoid a
circular dependency, since internal/testenv imports os/exec.
