Log:
  dpv(3): MFC r330943, r335264
  
  r330943:
  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.
  
  r335264:
  Fix comparison between pointer and char literal
