Revert "Revert "c-deps: fix assertion-enabled builds""

This reverts commit 6d6b5c4.

In the same PR I upgraded RocksDB to pull in
cockroachdb/rocksdb#59, which relaxes the
assertion whose failure led to the original revert.

Release justification: run `make testrace` in teamcity with rocksdb
assertions enabled to increase our bug-finding chances

Release note: None
