Wayland-drm: Fix not finding wl_drm_interface on systems with libglvnd
Wayland-drm: Fix not finding wl_drm_interface on systems with libglvnd

We do not want just any libEGL.so.1 we want mesa's libEGL.so.1 as that
is the only way which defines the wl_drm_interface symbol we need,
one systems with libglvnd libEGL.so.1 is a dispatcher library provided
by libglvnd and the actual mesa libEGL we want is named libEGL_mesa.so.0
so try that first.
