[Bug]: Single file mounts sometimes fail with EACCES

[dcantah]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

Virtualization.framework has a bug with opening hardlinks in some cases, which is how our single file mount idea is structured (we create a hardlink to the file they asked to share). It's being tracked in rdar://169481107. Keeping this open so we can revert back to our hardlink approach on some builds when it is fixed.

Current behavior

Sometimes opening a single file mount returns EACCES.

Expected behavior

Opening hardlinks in the guest to work, and not return EACCES.
