flock: make flock(1) work on NFSv4
To pleace an exclusive lock on a file, NFSv4 requires
the file to be opened RW because of the emulation of flock()
by fcntl():
http://www.spinics.net/lists/linux-nfs/msg18502.html
So instead of O_RDONLY, open the file in O_RDWR if access()
indicates it is possible (unless shared lock is requested).
