Filter subtrees and and benchmarks from coverage report

Remove leveldb baseline coverage gathering.

Added filter rules to remove all of the subtress (leveldb, secp256k1, ctaes, univalue) and
benchmarking from the coverage report. These items are unnecessary as we do not test for any
of the subtrees and benchmark coverage is unneeded.
