This CL is created as a best effort to migrate test targets to the new Android ownership model.
It is based on historical data from repository history and insights from git blame.
Given the nature of this effort, there may be instances of incorrect attribution. If you find incorrect or unnecessary
attribution in this CL, please create a new CL to fix that.

One turns out not to be used at all, and the pylintrc even uses the more
intention-revealing term in the machine readable part, just not the
comment!

Modules with a libbase dependency also need a liblog dependency now.
Fixes the linker-reloc-bench build target.

The benchmark creates a set of DSOs that mimic the work involved in
loading the current version of libandroid_servers.so. The synthetic
benchmark has roughly the same number of libraries with roughly the same
relocations.
Currently, on a local aosp_walleye build that includes recent performance
improvements (including the Neon-based CL
I3983bca1dddc9241bb70290ad3651d895f046660), using the "performance"
governor, the benchmark reports these scores:
