[Issue] Corrected mekset lines for Long Tom unit images

[Gribbly1]

Brief Description *

At some point the unit names for Long Tom trailers were rearranged, but the unit image mekset wasn't.

These are the existing rows:

exact "Mobile Long Tom Artillery Ammunition Trailer LT-MOB-25" "vehicles/Longtom_Trailer_Ammo.png"
exact "Mobile Long Tom Artillery Support Carriage LT-MOB-25" "vehicles/Longtom_Trailer_Support.png"
exact "Mobile Long Tom Artillery Ammunition Carriage LT-MOB-25F" "vehicles/Longtom_Trailer_Ammo.png"
exact "Mobile Long Tom Artillery Ammunition Loader Carriage LT-MOB-25F" "vehicles/Longtom_Trailer_Loader.png"
exact "Mobile Long Tom Artillery Support Carriage LT-MOB-25F" "vehicles/Longtom_Trailer_Support.png"
exact "Mobile Long Tom Artillery Drone Command Carriage LT-MOB-25F" "vehicles/Longtom_Trailer_Drone.png"

These are the corrected ones:

exact "Mobile Long Tom Artillery LT-MOB-25 (Ammunition Carriage)" "vehicles/Longtom_Trailer_Ammo.png"
exact "Mobile Long Tom Artillery LT-MOB-25 (Support Carriage)" "vehicles/Longtom_Trailer_Support.png"
exact "Mobile Long Tom Artillery LT-MOB-25F (Ammunition Carriage)" "vehicles/Longtom_Trailer_Ammo.png"
