[Backport to 1.1] wayland-info: Fix build without libdrm

wayland-info can optionally use libdrm to provide a description of the dmabuf format modifiers.

When not using libdrm however, the build fails because "dev_t" is not defined.

The definition of "dev_t" comes from <sys/types.h> which is included from <libdrm.h>, which is not included without libdrm support, hence the build failure.

Simply include <sys/types.h> unconditionally to make sure "dev_t" is defined regardless of libdrm support, to fix the build failure.

Closes: #6 (closed)

Fixes: 240cb739 - "Add support for linux_dmabuf version 4"
