The lockf() call in qemu_create_pidfile() aims at ensuring mutual
exclusion. We shouldn't close the pidfile on success, because that drops
the lock as well [1]:
"File locks shall be released on first close by the locking process
of any file descriptor for the file."
Coverity may complain again about the leaked file descriptor; let's
worry about that later.
