vnc: avoid deprecation warnings for SASL on OS X

Browse Source 
Apple has deprecated sasl.h functions in OS X 10.11.  Therefore,
all files that use SASL API need to disable -Wdeprecated-declarations.
Remove the only use that is outside vnc-auth-sasl.c and add the
relevant #pragma GCC diagnostic there.
