Use real exec on cfg(unix) targets

Closes https://github.com/rust-lang/miri/issues/2421

The standard library has a platform extension trait that lets us get the behavior we want on cfg(unix), so why not use it?

I tried this out and it produces the correct behavior in concert with nextest.

622613f957 Use real exec on cfg(unix) targets 
When cargo-miri is executed as a cargo test runner or rustdoc runtool,
external tools expect what they launch as the runner/runtool to be the
process actually running the test. But in the implementation, we launch
the Miri interpreter as a subprocess using std::process::Command. This
tends to confuse other tools (like nextest) and users (like the author).
What we really want is to call POSIX exec so that the cargo-miri process
becomes the interpreter.

So this implements just that; we call execve via a cfg(unix) extension
trait. Windows has no such mechanism, but it also doesn't have POSIX
signals, which is the primary tripping hazard this change fixes.

d905901d65 make miri a better RUSTC by default inside cargo-miri 
this requires a change in sysroot handling: miri driver now requires
MIRI_SYSROOT to be set when it is in 'target' mode, rather than relying on
`--sysroot` always being present.
