perf tools: Set thread->mg.machine in all places
We were setting this only in machine__init(), i.e. for the map_groups that
holds the kernel module maps, not for the one used for a thread's executable
mmaps.
Now we are sure that we can obtain the machine where a thread is by going
via thread->mg->machine, thus we can, in the following patch, make all
codepaths that receive machine _and_ thread, drop the machine one.
