ash: respect -p flag when command builtin is run with -v/-V
The command builtin should only check the default path, not $PATH,
when the -p flag is used along with -v/-V.
Based on commits 65ae84b (by Harald van Dijk) and 29ee27d (by Herbert
Xu) from git://git.kernel.org/pub/scm/utils/dash/dash.git).
