[oe] [meta-oe][PATCH] xpext: Allow the main package to be empty.

[Drew Moseley]

If xpext is included in a build (ie via dependency on mpv) then
builds of core-image-sato-sdk will fail with errors such as below.

Allowing the package to be empty fixes this.

     warning: Can't install mpv-dev-0.15.0-r0 at i586: Can't install xpext-dev-1.0+5-r0 at i586: no package provides xpext = 1.0+5-r0
