[PATCH] elf.h: Drop duplicate DT_RISCV_VARIANT_CC

[Palmer Dabbelt <palmer@rivosinc.com>]

I missed the update from last year that included these already, having
duplicates breaks the build due to redefinition errors like

    elf/elf.h:4013: error: macro STO_RISCV_VARIANT_CC redefined
    elf.h:3941: note: location of previous definition

Reported-by: Joseph S. Myers <joseph@codesourcery.com>
Fixes: 117e8b341c ("riscv: Resolve symbols directly for symbols with STO_RISCV_VARIANT_CC.")

bulid-many-glibcs is still churning and might take a bit, but looks like
this was just a silly mistake on my end.  I'm pretty confident this
fixes the issue, but happy to wait for the tests to finish given that I
just screwed this up.  That was before coffee, though, so maybe I can
avoid some of the blame... ;)
