Roland Shoemaker 953d1feca9 all: introduce and use internal/execabs
Introduces a wrapper around os/exec, internal/execabs, for use in
all commands. This wrapper prevents exec.LookPath and exec.Command from
running executables in the current directory.

All imports of os/exec in non-test files in cmd/ are replaced with
imports of internal/execabs.

This issue was reported by RyotaK.

Fixes CVE-2021-3115
Fixes #43783
