c-deps: bump rocksdb for unique cache IDs on Windows

Picks up cockroachdb/rocksdb#58.

We found a corruption caused by multiple FAT32 files assigned the same
block cache key prefix. We don't know the extent to which this problem
affects other filesystems or other Windows file ID generation mechanisms.
We decided to turn off the reliance on filesystem for generating cache
keys on Windows. Instead we use randomization per table reader. This
would cause a performance penalty for use cases that open multiple table
readers per file, but I believe cockroach is not such a use case.

Fixes cockroachdb#40918, fixes cockroachdb#40950.

Release justification: Prevents corruption on some Windows filesystems

Release note: None
