Fix finding PBR materials

[nkoenig]

While loading https://app.ignitionrobotics.org/OpenRobotics/fuel/models/DronePlatformX1 I would see the following errors:

[Err] [SystemPaths.cc:444] Could not resolve file [./materials/textures/DronePlatformX1_Roughness.jpg]
[Err] [SceneManager.cc:465] Unable to find file [./materials/textures/DronePlatformX1_Roughness.jpg]
[Err] [SystemPaths.cc:444] Could not resolve file [./materials/textures/DronePlatformX1_Albedo.jpg]
[Err] [SceneManager.cc:498] Unable to find file [./materials/textures/DronePlatformX1_Albedo.jpg]

[Err] [SceneManager.cc:509] Unable to find file [./materials/textures/DronePlatformX1_Normal.jpg]

This resolves those errors.

This removes the error messages for me, but I still am not seeing the platform. For example, here's what I see after running

ign launch competition.ign worldName:=simple_cave_01 circuit:=cave robotName1:=X1 robotConfig1:=X1_SENSOR_CONFIG_1 robotName2:=X2 robotConfig2:=CERBERUS_RMF_SENSOR_CONFIG_1 marsupial1:=X1:X2

(related to osrf/subt#763):

If you are running a source build, could you try updating everything?
