[ELF][RISCV] Don't set cheriCapCallRel

This was never on CHERI-RISC-V even when we used .captable, as we passed
R_CHERI_CAPABILITY_TABLE_INDEX to ensure the relocation was in .rela.dyn
and thus would also use cheriCapRel rather than cheriCapCallRel. Now the
normal .got is used instead there isn't even a path that could use this.
