syscall.2: Update name of syscall instruction for riscv

As reported by Florin:

    In the first table, for the riscv Arch/ABI, the instruction
    should be ecall instead of scall.

    According the official manual, the instruction has been
    renamed.

    "The SCALL and SBREAK instructions have been renamed to
    ECALL and EBREAK, respectively. Their encoding and
    functionality are unchanged."
