  1. riscv64: Mount tmpfs to support unit-tests expecting /tmp 

    As `9p` rootfs documented [1], mount a `tmpfs` onto `/tmp` could avoid
`E: Unable to determine file size for fd 7 - fstat (2: No such file or
directory)`.

And various unittests in `linux-loader`, `vm-memory` and etc. explicitly
expect `/tmp` to exist, and were failing on riscv because no `tmpfs` was
mounted.

Modify `/etc/fstab` to apply the mount operation during boot.

  2. riscv64: Improve command forwarding 

    Previous implementation uses `netcat` to test existence of
pre-configured target port, but that port is occupied in advance of
`sshd` inside VM is ready.

Replace `netcat` with `ssh` with `ConnectTimeout` set to directly verify
the connectivity of `sshd`.
