Subject: [PATCH] Deflake BlobDBTest.SnapshotAndGarbageCollection (#8444)

Summary:
This test case has been failing occasionally due to automatic
compactions kicking in, resulting in GC generating additional
blob files that the test did not expect. Disabling automatic
compactions to get rid of this flakiness.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8444

Test Plan: `gtest-parallel --repeat=1000 ./blob_db_test --gtest_filter="BlobDBTest.SnapshotAndGarbageCollection"`
