  [ELF] Rewrite R_RISCV_ALIGN nops when r.addend%4 != 0

For RVC, GNU assembler and LLVM integrated assembler add c.nop followed by a
sequence of 4-byte nops. Even if remove % 4 == 0, we have to split one 4-byte
nop and therefore need to write the code sequence, otherwise we create an
incorrect c.unimp.
