man: fix wrong KillUserProcesses= default in systemd-run(1)

systemd-run(1) hard-coded "the default" wording for KillUserProcesses=, but the
actual compile-time default is determined by the -Ddefault-kill-user-processes=
meson build option, which distributions set differently at packaging time.

Consistent with logind.conf(5).
