Fix bad error messages from dpv(3)

Before = dpv: <__func__>: posix_spawnp(3): No such file or directory
 After = dpv: <path/cmd>: No such file or directory

Most notably, show the 2nd argument being passed to posix_spawnp(3)
so we know what path/cmd failed.

Also, we don't need to have "posix_spawnp(3)" in the error message
nor the function because that can [a] change and [b] traversed using
a debugger if necessary.
