Revert "bionic: Disable arm32 cpu_target_featuers test"

This reverts commit 3b3b356.

Reason for revert: This test was disabled because it was failing on arm32 due to a bad hardcoding. We fixed the hardcoding in llvm/llvm-project#122969 and cherry-picked it in aosp/3453341 so the change is in clang-r547379. We can revert this CL and re-enable the test.
