feat(status): detect PCSX2 for game mode

PCSX2 joins gamescope, Steam and DuckStation in the game detector, so
presentation is set automatically while a PS2 game runs and the idle
lock, DND and breaktimer stay out of the way.

The binary is /usr/bin/pcsx2-qt, the same -qt shape as duckstation-qt,
so it takes the same pgrep -x exact name match and cannot self-match the
way the bracketed steam pattern has to guard against.

Verified against the real emulator rather than a stand-in: with
pcsx2-qt running, status.gaming reads 1.
