QLockFile: decide on locking strategy per path
It is filesystem dependent if flock and fcntl locks are independent or
the same underlying lock (which causes getting the second lock to fail).
A temporary file in /tmp might be on a local file system and pass
while the lock file is placed on NFS and fail with:
setNativeLocks failed: Resource temporarily unavailable
Instead check for lock conflicts per path and cache the result.
