Commit 56143ea63 (ash: code shrink: eliminate pstrcmp1()) changed
the layout of struct builtincmd so the name member points to the
start of the name, not the flag in the first element of the string.
This broke the help builtin and tab completion of builtins.

Remove the unnecessary '+ 1' in ash_command_name() and helpcmd().

ash_command_name                                      92      91      -1
helpcmd                                              106     102      -4
