maint: adjust INT_BUFSIZE_BOUND usage for maintainability

* src/tail.c (xlseek): Give INT_BUFSIZE_BOUND a variable name,
not a type name.
* src/ls.c (gobble_file, format_user_or_group_width): Likewise.
* src/head.c (elide_tail_bytes_pipe): Likewise.
(elide_tail_lines_seekable, main): Likewise.
[This change is not complete -- there are doubtless other uses
that can be updated in the same way.]
