Auto merge of #129640 - saethlin:unignore-android-in-alloc, r=<try>

Re-enable android tests/benches in alloc/core This is basically a revert of #73729. These tests better work on android now; it's been 4 years and we don't use dlmalloc on that target anymore. r? `@ghost` try-job: arm-android try-job: dist-android
