Bug#1102457: tightvnc uselessly links -lcrypt

[Helmut Grohne <helmut@subdivi.de>]

Source: tightvnc
Version: 1:1.3.10-9
Tags: patch
User: helmutg@debian.org
Usertags: libcrypt-unused

tightvnc links -lcrypt without using any of its symbols. As we consider 
dropping libcrypt-dev from build-essential, this may cause a FTBFS. 
Consider dropping the unnecessary linkage already.
