[Qemu-devel] [PATCH buildfix for-2.0] linux-user: Fix build if headers don't define _LINUX_CAPABILITY_VERSION_1

[Peter Maydell]

Older kernel headers don't define _LINUX_CAPABILITY_VERSION_1.
Switch to using the older _LINUX_CAPABILITY_VERSION; newer headers
still define this for source compatibility.
