Vito Caputo db3f45e2d2 basic: use _unlocked() stdio in strip_tab_ansi() (#6385) 
Trivial performance boost by explicitly bypassing the implicit
locking of stdio.

This significantly affects common cases of `journalctl` usage:

 Before:

  # time ./journalctl -b -1 > /dev/null
   real    0m26.628s
   user    0m26.495s
   sys     0m0.125s

  # time ./journalctl -b -1 > /dev/null
   real    0m27.069s
   user    0m26.936s
   sys     0m0.134s

  # time ./journalctl -b -1 > /dev/null
   real    0m26.727s
   user    0m26.607s
   sys     0m0.119s

 After:

  # time ./journalctl -b -1 > /dev/null
   real    0m23.394s
   user    0m23.244s
   sys     0m0.142s

  # time ./journalctl -b -1 > /dev/null
   real    0m23.283s
   user    0m23.160s
   sys     0m0.121s

  # time ./journalctl -b -1 > /dev/null
   real    0m23.274s
   user    0m23.125s
   sys     0m0.144s
