auth: Remove support for HAVE_TRUNCATED_SALT from pass_check.c

The comments indicate that this was needed for HP-UX at one point, but
the configure code was never ported to WAF.

-   This bit of code was derived from the UFC-crypt package which
-   carries the following copyright
-
-   Modified for use by Samba by Andrew Tridgell, October 1994
-
-   Note that this routine is only faster on some machines. Under Linux 1.1.51 
-   libc 4.5.26 I actually found this routine to be slightly slower.
-
-   Under SunOS I found a huge speedup by using these routines 
-   (a factor of 20 or so)
-
-   Warning: I've had a report from Steve Kennedy <steve@gbnet.org>
-   that this crypt routine may sometimes get the wrong answer. Only
-   use UFC_CRYT if you really need it.
