jiri: Simplify usage and impl of jiritest.NewFakeJiriRoot

The previous usage of NewFakeJiriRoot was annoying; you'd need to
check for errors, then defer a function to perform cleanup, which
also needed error checking.  The new implementation calls t.Fatal
to fail the test if any errors occur.  This makes the usage a
simple two lines:

fake, cleanup := jiritest.NewFakeJiriRoot(t)
defer cleanup()

Also replaced some uses of jiritest.NewX_DeprecatedEnv with calls
to NewFakeJiriRoot.  I've replaced all the "easy" ones; all of
the remaining ones rely on the profiles logic, which needs
cleanup of its own before more progress can be made.

Here are the files with remaining uses of NewX_DeprecatedEnv,
because of their usage of profiles:

jiri/profiles/env_test.go
jiri/profiles/manifest_test.go
x/devtools/jiri-test/internal/test/go_test.go
x/devtools/jiri-api/api_test.go
x/devtools/jiri-go/go_test.go
x/devtools/gologcop/gologcop_test.go
