[ptxdist] [RFC 1/2] libva-headers: new package

[Philipp Zabel <p.zabel@pengutronix.de>]

Add a stripped down version of the libva package that installs only the
headers and pkgconfig file required by Mesa.
This avoids a circular dependency between Mesa, which requries libva
headers, and libva, which may require Mesa to build GLX support.
