nall: Linux does support file creation time

[jeffythedragonslayer]

I saw Screwtape mention this as part of a good first issue somewhere, thanks for pointing that out about statx

[Screwtapello]

This PR has a change to the comment, but doesn't actually try to call statx(). Was that deliberate, or did you forget to push a commit?

[jeffythedragonslayer]

Yes it was deliberate, I haven't delved deep into the codebase yet to actually fix the call. Just trying to stop people who are browsing the codebase from getting wrong information into their heads for now.

Please consider adding an implementation that uses statx; it seems odd to merge a commit that makes reference to another possibility without providing it.

This also does depend on what you want the minimum required Linux kernel version for the emulator to be. statx was introduced in the 4.11 Linux kernel, which is now over 6 years old so is probably needs suiting for most people, but may effectively increase the minimum kernel version, and the implementation of this might need to keep that in mind.

In fact mentioning a minimum Linux kernel version/maximum Linux kernel age the emulator wants to support might be nice to have in the README for situations like this.
