/proc/PID/smaps: consistent whitespace output format
The keys in smaps output are padded to fixed width with spaces. All except for THPeligible that uses tabs (only since commit c06306696f83 ("mm: thp: fix false negative of shmem vma's THP eligibility")). Unify the output formatting to save time debugging some naïve parsers. (Part of the unification is also aligning FilePmdMapped with others.)
