[PATCH xserver 3/3] meson: Add pixman-1 to required modules in xorg-server.pc

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

pixman headers will be included for builds of external modules against
the xorg-server SDK. Make sure pixman is listed as a required module so
that the correct CFLAGS will be added.

Note that the xorg-server.pc generated by the autotools-based build has
many more modules listed, but this seems to be enough to build at least
some of the external drivers against an X server built with Meson (I've
tested with xf86-input-libinput, xf86-video-nouveau and xf86-video-ati).
