gpg: Cleanup of dek_to_passphrase function (part 1).

Browse Source 
* g10/passphrase.c (passphrase_to_dek_ext): Remove args CUSTDESC and
CUSTPROMPT.  Merge into the passphrase_to_dek wrapper.
(passphrase_get): Remove args CUSTOM_DESCRIPTION and CUSTOM_PROMPT.
--

The function is nowadays only used for symmetric encryption.  Thus we
do not need all the former advanced stuff.
