[v4,1/1] qtest: Fix the bug about disable vnc causes "make check" fail

When we disable vnc from "./configure", QEMU can't use the vnc option.
So qtest can't use the "vnc -none ", otherwise "make check" fails.
If QEMU uses "-display none", "-vnc none" is excrescent, So we just need to drop it.

 v2: Consolidate VNC macro's #ifdef'ery to one central point (tests/libqtest.c).
 v3: Fix the spelling and terminology error: "s/disabling/disable; s/the\ qemu/QEMU; s/hangs/fails;"
 v4: If QEMU uses "-display none", "-vnc none" is excrescent, So we just need to drop it.
