riscv: correct riscv_insn_is_c_jr() and riscv_insn_is_c_jalr()
The instructions c.jr and c.jalr must have rs1 != 0, but
riscv_insn_is_c_jr() and riscv_insn_is_c_jalr() do not check for this. So,
riscv_insn_is_c_jr() can match a reserved encoding, while
riscv_insn_is_c_jalr() can match the c.ebreak instruction.
Rewrite them with check for rs1 != 0.
