error code E0080 is no longer printed with MIRI error message

Thanks to help from @bjorn3, @RalfJung, and @oli-obk on issue #1035 , I fixed the miri code so that error code **E0080** is no longer printed out for MIRI evaluation errors. I tested my code in my Linux machine as below.
![image](https://user-images.githubusercontent.com/10286488/68264744-e71e6c80-0017-11ea-9028-f83e19164ea2.png)

Remaining concern is whether the variable name `new_tcx` which I used is misleading or not.

change cargo-miri.rs to fix issue #978

In Windows 10, there was an issue with building MIRI locally and getting it running,
due to unpredictable backslash escaping issues in paths.
I added a code snippet that would only be compiled in Windows OS, which replaces all backslashes in paths to slashes.
This fix should only affect Windows users.
Building and testing MIRI locally now works fine after the fix.

I think there is no way to do proper testing of this other than checking that miri does not crash when calling `clock_gettime`.

Write name and value for each env var

In order to res0lve https://github.com/rust-lang/miri/issues/756 is necessary to have the whole `"NAME=VALUE"` sequence of bytes written into memory instead of just the value.

This change does not affect the interface of the `shim::envs::EnvVars` type in any way.

Use host's rng when communication is enabled

This uses the host's randomness when the communication enabled flag is used. I am not sure about the error handling. I was thinking about fallbacking to `rand` if `getrandom` fails and also print something so the user knows miri is not using the host's rng because it failed. Let me know what you think.
