ui/gtk: fix crash at startup when no console is available 

This patch fixes a segfault at QEMU startup, introduced in a08156321a.
gd_vc_find_current() return NULL, which is dereferenced without checking it.

While at it, disable the whole 'View' menu if no console exists.

Reproducer: qemu-system-i386 -M none -nodefaults
