ash: fix tab completion

The initial index for the command and alias tables was incorrect.

Change since 3165054d2:

function                                             old     new   delta
ash_command_name                                       -     155    +155
hush_command_name                                      -     110    +110
complete_cmd_dir_file                                876     880      +4
ash_builtin_name                                      17       -     -17
hush_builtin_name                                     38       -     -38
