[meta-virtualization] [PATCH] libvirt: add dtrace pkgconfig option

If the host machine has dtrace, or systemtap development libraries
installed, libvirt will detect their headers and enable dtrace probe
But since we don't have a dependency on dtrace, the build will fail
| compilation terminated.
| In file included from ./internal.h:297:0,
| from util/bitmap.h:27,
| from util/bitmap.c:33:
| ./libvirt_probes.h:9:21: fatal error: sys/sdt.h: No such file or directory
There are three problems:
- a host contamination issue
- dtrace/probes being automatically enabled
- a lack of integrated systemtap/dtrace solution
Fixing any of the above will make the problem go away, to fix currently
broken builds, we can fix the problem by adding dtrace as a PACKAGECONFIG
option, and leaving it disabled. This change doesn't add a dtrace/systemtap
dependency to the config entry, since they haven't been confirmed at this
In the future, we should either fix the host contamination or do a full
systemtap/dtrae integration, but for now, simply disabling it is the

Sending this patch out for comment, it's minor change. If there are no objections,
I'll push it into the repository tomorrow.
