Fix lock permission

[cih9088]

All files except lock file have proper permission obeying ACL property if it is set.

If the cache directory has ACL property, it should be respected instead of just using umask for permission.
To fix it, just create a lock file and pass the created mode.

By creating a lock file with touch() before FileLock create it with mode,

• if ACL is not set, same as before
• if ACL is set, ACL is respected

If it is acceptable, it should be also applied to huggingface_hub I guess.
