linux: Add generic struct stat {}

Browse source 
Add generic implementation of struct stat {} imported from Linux 6.13.y
commit 27560b371ab8 ("fs: pack struct kstat better"). This can be used
by filesystem code imported from elsewhere. Now struct stat {} becomes
available on all supported architectures.
