ci: build the release mode tests with `-C target-cpu=native` (#11192)
# Which issue does this PR close?
- follow up to review discussion on
https://github.com/apache/arrow-rs/pull/10136
# Rationale for this change
The "Test Release Mode" job in `arrow.yml` compiles with the default
`x86_64` target, which only enables SSE2:
```
$ rustc | grep target_feature
target_feature="fxsr"
target_feature="sse"
target_feature="sse2"
```
So any code gated on `cfg(target_feature = ...)`, such as the AVX / AVX2
paths in `arrow-arith/src/aggregate.rs` and
`arrow-array/src/array/union_array.rs`, or the BMI2 `pext` path proposed
in #10136, is never compiled or tested on CI.
# What changes are included in this PR?
Add `-C target-cpu=native` to `RUSTFLAGS` for the `linux-release-test`
job, so we test with every instruction set extension of the runner CPU.
# Are these changes tested?
By CI: this job should now build and run the tests with the target
features enabled.

# Are there any user-facing changes?
No
