Subject: lsfd: test: Adapt test cases for pidfs
Git-repo: https://github.com/util-linux/util-linux.git
Git-commit: 04db2ba9008e9635286b1aafc8ecd9533a0a91bf
Patch-mainline: yes
References: kernel 6.9

On Linux >= 6.9, pidfds are from pidfs instead of anonymous inode.
Thus:

STTYPE is REG on Linux >= 6.9, UNKN on Linux < 6.9.

KNAME is pidfd:[inode number] on Linux >= 6.9, anon_inode:[pidfd] on
Linux < 6.9.

And ainode_class test cannot work on Linux >= 6.9, just skip this sub
test if STTYPE is REG.
