  [ELF] scanRelocations: support .crel.eh_frame

Follow-up to #98115. For EhInputSection, RelocationScanner::scan calls
sortRels, which doesn't support the CREL iterator. We should set
supportsCrel to false to ensure that the initial_location fields in
.eh_frame FDEs are relocated.

(cherry picked from commit a821fee312d15941174827a70cb534c2f2fe1177)
