[PM] Switch Dynamic Tcmalloc to CrOS only
Finch experiments have shown this has more of a benefit on CrOS rather than
linux. We suspect this is because CrOS devices tend to have much lower RAM
configurations. So we've decided to ship only on CrOS.
This CL will officially make this feature only available to CrOS.
