package/libvncserver: needs dynamic library

Disable libvncserver for static builds and drop second patch following
upstream feedback on patch fixing openssl issue:
https://github.com/LibVNC/libvncserver/pull/319

This will also fix build failure when building statically with libgcrypt

Don't update x11vnc, the reverse dependency of libvncserver, because
BR2_PACKAGE_XORG7 already depends on !BR2_STATIC_LIBS

Fixes:
