[Libguestfs] [PATCH] run: Don't fail on missing LIBGUESTFS_PATH if --disable-appliance

[Hilko Bengen]

Set LIBGUESTFS_PATH to the default value compiled into and output a
warning to STDERR, instead.

The previous behavior caused the build to abort when trying to build
the sysprep documentation -- without much of a hint of what went
wrong.

When LIBGUESTFS_PATH was not set, test-events.sh would fail.
