Summary: Currently, the local-only path fails about 50% of the tests, which means that: a) nobody is using it; and b) the remote debugging path is much more stable. This commit removes the local-only linux debugging code (ProcessLinux) and makes remote-loopback the only way to debug local applications (the same architecture as OSX). The ProcessPOSIX code is moved to the FreeBSD directory, which is now the only user of this class. Hopefully, FreeBSD will soon move to the new architecture as well and then this code can be removed completely. Test Plan: Test suite passes via remote stub.
