meson: fix android vulkan build

Android doesn't have `pthread_cancel()` and is unlikely to ever
implement it [1], but `wsi_common_display.c` needs it (or an
alternative).

Let's just disable the platform on Android (as it used to be
before 448eb19158).

Fixes: 448eb19158 ("vulkan: automatically compile the `display` platform when available")
