[pushed: r15-7515] jit: add "final override" to diagnostic sink [PR116613]

[David Malcolm]

I added class jit_diagnostic_listener in r15-4760-g0b73e9382ab51c
but forgot to annotate one of the vfuncs with "override".

Fixed thusly.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r15-7515-g6ac313525a1fae.

gcc/jit/ChangeLog:
	PR other/116613
	* dummy-frontend.cc
	(jit_diagnostic_listener::on_report_diagnostic): Add
	"final override".
