3566353 ci: remove compiled-but-unused BDB from MSAN job (fanquake) Pull request description: Self-compiled BDB was added to this job as opposed to using depends BDB [due to linking issues](bitcoin#18288 (comment)), however the compiled BDB is not actually used. Remove it for now, given we don't actually lose any coverage (note that BDB is also not currently used in the naitve MSAN fuzz job or for [OSS Fuzz](https://github.com/google/oss-fuzz/blob/master/projects/bitcoin-core/build.sh#L32) builds). In future, we can use depends BDB, however introducing it now will cause false positives, which can be fixed by upgrading the versions of Clang / LLVM we use, however upgrading to those newer versions causes other issues, which appear in standard library code, and require more involved suppressing, which can be solved in a follow up or another PR i.e bitcoin#23008. Top commit has no ACKs. Tree-SHA512: 9e8fdd95246cafa27cda7bcf0641b428d4573f6748ecdf07cc6205a64351db22ba383ec943e88a69df3694ccb9f125d994b64345a4e44fb6fea4a014504760d1

While CI passes, I've changed this to use matching versions of clang and libcxx, since it is unclear if mismatching versions are supported. |

The MSan issue was fixed in llvm-10. We have been using llvm-12 since bitcoin#23008.
