kconfig/nconf: Fix hang when editing symbol with a long prompt
Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters. dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid. It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.
The additions in the offset calculations also don't match the intended
size of the window.
Limit the window size and calculate the offset similarly to
show_scroll_win().
