RISC-V: Remove R_RISCV_GNU_VTINHERIT/R_RISCV_GNU_VTENTRY
They were legacy relocation types copied from other ports. The related
-fvtable-gc was removed from GCC in 2003.
The associated assembler directives (.vtable_inherit and .vtable_entry)
have never been supported by the RISC-V port. Remove related ld code.
