[rc/sway] bind XF86PowerOff to prompt for system exit action

- (l)ock
- (e)xit sway
- (s)uspend
- (h)ibernate
- (r)eboot
- (S)hutdown

need to inhibit systemd's handling of the power button using
systemd-inhibit (or alternatively and less elegantly by modifying
/etc/systemd/logind.conf, which i didn't want to do)
