("[PATCH] cpu: fix memleak of 'halt_cond' and 'thread'")

I saw various sanitizer errors when running check-qtest-ppc64. While
I could just turn off sanitizers, I decided to tackle them this time.

Unfortunately, GLib does not free test data in some cases so some
sanitizer errors remain. All sanitizer errors will be gone with this
patch series combined with the following change for GLib:
