libsubcmd: Avoid SEGV/use-after-free when commands aren't excluded
The array shortening may perform unnecessary array copies.
Before commit 657a3efee43a ("lib subcmd: Avoid memory leak in
exclude_cmds") this was benign, but afterwards this could lead to a
SEGV.
Fixes: 657a3efee43a29d1 ("lib subcmd: Avoid memory leak in exclude_cmds")
