common: Remove simple password query error codes.

Browse Source 
* common/simple-pwquery.h: Remove mapping function.  Move all
definitions of status codes...
* common/simple-pwquery.c: ... here, and define them to meaningful gpg
error values.
* agent/preset-passphrase.c (preset_passphrase): Use error code as-is.
(forget_passphrase): Likewise.
* tools/symcryptrun.c (confucius_get_pass): Likewise.
