[media benchmarking] Replace myself with John and Frank.

It's best to have multiple owners in the event of OOO,
so I have nominated John as an additional owner of
load_library_perf_tests and Frank as an additional owner
of media_perftests.

Owners are responsible for understanding how these tests
are important for the product. They do not need to
understand how the tests are run or how the infrastructure
works.

I am leaving Google.
