given this job is using nightly and some comments suggested rustc was getting confused about what could be reused / not ensure this target isn't shared with stable versions

Rationale for this change
The arrow CI tests that rely on nightly are crashing with some sort of rustc internal compiler error due to the internal serialization format changing.
for example: https://github.com/apache/arrow-rs/runs/4468916693?check_suite_focus=true
Also on master: https://github.com/apache/arrow-rs/runs/4474503693?check_suite_focus=true
As @b41sh pointed out #779 (comment), it seems to be a bug in rust: rust-lang/rust#91663
What changes are included in this PR?
Use a new cache key (and thus force clean builds)
Are there any user-facing changes?
No -- CI only
