bash_completion: fix ls invocation

As Daniel Hahler reports in bug #944:

  etc/bash_completion.d/vzctl.sh.in uses "ls" for "--ostemplate" and
  "--config|--applyconfig".

  This might cause strange behavior, if a funky alias for "ls" is defined,
  e.g. some coloring etc.

Fix this by using bash built-in "command" which should not use alias.
