Marc-André Lureau 35f7f3fb5c util: use fcntl() for qemu_write_pidfile() locking 
Daniel Berrangé suggested to use fcntl() locks rather than lockf().

'man lockf':

   On Linux, lockf() is just an interface on top of fcntl(2) locking.
   Many other systems implement lockf() in this way, but note that
   POSIX.1 leaves the relationship between lockf() and fcntl(2) locks
   unspecified.  A portable application should probably avoid mixing
   calls to these interfaces.

IOW, if its just a shim around fcntl() on many systems, it is clearer
if we just use fcntl() directly, as we then know how fcntl() locks will
behave if they're on a network filesystem like NFS.
