daemon: Suppress valgrind warnings from read_pidfile().

The version of valgrind I have in my test VMs doesn't know what F_GETLK
does, so it complains that l_pid is uninitialized even though fcntl sets
it.  Initializing it ourselves before calling the function avoids a series
of false-positive warnings about use of uninitialized data.
