Vulkan validation layer description no longer contains an absolute path to the layer shared object

[expipiplus1]

Describe the bug

The validation layer shared object is no longer findable unless it's in the library search path (add it to LD_LIBRARY_PATH for a quick workaround).

The update included here: #206384 has made it so that this patch no longer does what it's intending to

nixpkgs/pkgs/development/tools/vulkan-validation-layers/default.nix

Lines 40 to 44 in afc9820

	# Include absolute paths to layer libraries in their associated
	# layer definition json files.
	postPatch = ''
	sed "s|\([[:space:]]*set(INSTALL_DEFINES \''${INSTALL_DEFINES} -DRELATIVE_LAYER_BINARY=\"\)\(\$<TARGET_FILE_NAME:\''${TARGET_NAME}>\")\)|\1$out/lib/\2|" -i layers/CMakeLists.txt
	'';

Steps To Reproduce

• checkout nixpkgs before vulkan-sdk: 1.3.231.0 -> 1.3.236.0 #206384

• grep library_path $(nix-build --no-out-link -A vulkan-validation-layers)/share/vulkan/explicit_layer.d/VkLayer_khronos_validation.json

• observe that an absolute path to libVkLayer_khronos_validation.so is printed

• repeat with a version after vulkan-sdk: 1.3.231.0 -> 1.3.236.0 #206384 and observe that it's not longer absolute
