[test] Test with rs-ninja.sh

sh_wrapper, sh_wrapper_test (bazel rules): no longer join commands with
'--', so wrappers that use these (most) will add it to the end of their
token lists.

rs-ninja.sh is one such script that wraps as a prefix to ninja without
'--'.
Add unit-tests that ensure propagation of exit status through
rs-ninja.sh.
Update end-to-end tests to use rs-ninja.sh, by passing it as an extra
prefix binary to the ninja_test rule (repeating --ninja_bin).
This turned out to be simpler than generating a sh_binary that fused
together rs-ninja.sh and prebuilt/ninja.

ninja_tests: add a clang-expect-fail test (compile error).
duplicate many tests named _with_rs that use rs-ninja.sh.
End-to-end tests with rsproxy should use this, instead of the variants
named without _with_rs.
This will ensure proper communication through the RSPROXY_FIFO
variable.

Using all of the above, able to create a non-sandboxed,
network-accessed, end-to-end bazel test of rsproxy and ninja that
connect to a real service (instead of fake_resultstore server)!
