vnc: Fix packed boolean struct members 

This patch fixes warnings reported by splint:

For variables which are packed in a single bit, a signed data type
like 'int' does not make much sense.

There is no obvious reason why the two values should be packed,
so I removed the packing and changed the data type to bool
because both are used as boolean values.

v2:

Some versions of gcc complain after this modification,
for example gcc (Debian 4.4.5-8) 4.4.5):

ui/vnc-auth-sasl.c: In function ‘vnc_sasl_client_cleanup’:
ui/vnc-auth-sasl.c:34: error: suggest parentheses around assignment used as truth value

Obviously, the compiler does not like code which does
bool = unsigned = bool = 0

Splitting that code in three statements works.
