wolf: fix auto steam-setup-frontends invocation ($0 resolution)

install_wolf()'s new auto-wire-up called it as 'bash manage.sh
steam-setup-frontends', which sets $0 inside manage.sh to the bare
string 'manage.sh' (no path). steam-setup-frontends re-invokes itself
per emulator via "$0" steam-add-nonsteam-game ..., and a bare
'manage.sh' with no '/' triggers a $PATH lookup instead of running the
local file — confirmed live: every emulator already downloaded (Azahar,
PCSX2, Cemu, Dolphin) failed with 'manage.sh: command not found' and
the run ended with a false "No emulator AppImages found" even though
they were sitting right there in emulators/.

Invoking it as './manage.sh' instead keeps $0 as './manage.sh', which
resolves correctly for the nested re-invocation, matching how every
other caller in this file already runs it.
