libfdt: tests: Update test case for overlay_bad_fixup

Changed the target DTS from overlay_base_no_symbols.test.dtb to overlay_base_manual_symbols.test.dtb.
This ensures that the test case doesn't exit prematurely due to the absence of label-linked phandle in the symbols node.
The update guarantees that the test case appropriately checks the validity of the fixup string linked to the label, as intended.
