GLib uses abort(3) to exit failed test cases. As a result, the pid file and
UNIX domain sockets for a running test are leaked upon failure.
Since abort(3) does not call atexit(3) handler functions, we could set up a
SIGABRT handler that performs cleanup. But there are other conditions where
processes die, like SIGSEGV or SIGBUS.
Let's unlink pid files and UNIX domain sockets as soon as the QEMU process has
initialized and connections have been made. This eliminates the possibility of
leaking these files.
Note that the actual QEMU process is orphaned when a test case fails. This
series does not fix that problem.
