hush: code shrinktab_completion

Handle both arrays of builtin as the same type.

function                                             old     new   delta
ash_command_name                                       -     154    +154
hush_command_name                                      -      97     +97
complete_cmd_dir_file                                876     880      +4
ash_builtin_name                                      17       -     -17
hush_builtin_name                                     38       -     -38
------------------------------------------------------------------------------
(add/remove: 2/2 grow/shrink: 1/0 up/down: 255/-55)           Total: 200 bytes

In the case where ash is disabled and hush is enabled but with support
for functions disabled this reduces the bloat from 31 to 6 bytes.
