vfs: use UAPI types for new struct delegation definition

Browse Source 
Using libc types and headers from the UAPI headers is problematic as it
introduces a dependency on a full C toolchain.

Use the fixed-width integer types provided by the UAPI headers instead.

Fixes: 1602bad16d ("vfs: expose delegation support to userland")
Fixes: 4be9e04ebf ("vfs: add needed headers for new struct delegation definition")
