Reproduce llvm-cov with nextest flag error.

Works with nextest

[nix-shell:~/projects/llvm-cov-err]$ cargo nextest run -E "not package(exclude)"
   Compiling exclude v0.1.0 (/home/noel/projects/llvm-cov-err/exclude)
   Compiling include v0.1.0 (/home/noel/projects/llvm-cov-err/include)
    Finished test [unoptimized + debuginfo] target(s) in 0.87s
    Starting 1 tests across 2 binaries
        PASS [   0.001s] include::bin/include test::include_test
------------
     Summary [   0.002s] 1 tests run: 1 passed, 0 skipped

Fails with llvm-cov wrapper

[nix-shell:~/projects/llvm-cov-err]$ cargo llvm-cov nextest run -E "not package(exclude)"
error: error: Found argument '-E' which wasn't expected, or isn't valid in this context

        If you tried to supply `-E` as a value rather than a flag, use `-- -E`

USAGE:
    cargo llvm-cov run [OPTIONS] [-- <ARGS>...]

For more information try --help

Fails with llvm-cov wrapper using workspace and exclude flags
