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
