Test ubuntu_perf_fixes.sh to 100%, take it off the allowlist (86 -> 85)
81/81 lines through run_all.sh at --min 100, exit 0, and
check_shell_coverage.sh passes with the allowlist line already deleted.

59 assertions over 14 cases across all four functions: the sysctl
drop-in with both the "already applied" skip and the documented-default
fallback for an unreadable sysctl; both NVIDIA branches, since the
helper-service path and the standalone fallback write different units
and different undo lines; earlyoom install / already-installed /
config-backup; and fix_failed_sssd for none, all five and exactly one
failed unit -- that last one matters because the detection loop breaks
at the first failure while the masking loop re-checks each unit, so a
naive implementation would mask all five.

The four write targets are now behind overrides defaulting to the real
paths. The add_undo lines deliberately KEEP their literal /etc paths and
are asserted to: the undo script runs on the real system, so seaming
those would have written an undo that removes nothing. Neither
/etc/sysctl.d/99-performance-tuning.conf nor /etc/default/earlyoom
exists after the suite runs.

bt_audio.sh re-measured at 127/127 with the new files present -- that
canary runs after every addition to this suite now, because a test file
silently broke it once already.

The handoff is rewritten for the one remaining lib.
