mm,thp: fix smaps THPeligible output alignment
Extract from current /proc/self/smaps output: Swap: 0 kB SwapPss: 0 kB Locked: 0 kB THPeligible: 0 ProtectionKey: 0 That's not the alignment shown in Documentation/filesystems/proc.rst: it's an ugly artifact from missing out the %8 other fields are using; but there's even one selftest which expects it to look that way. Hoping no other smaps parsers depend on THPeligible to look so ugly, fix these.
