vzctl: add 'suspend' and 'resume' aliases

- suspend is the same as chkpnt
- resume is the same as restore

bash-completion script and man page modified accordingly.

NOTE we are not patching vzmigrate script, since it calls vzctl
on the other side and there could be an older vzctl version that is
not aware of these new aliases.
