tests/tcg: Stop using exit() in the gdbstub testcases

GDB 15 does not like exit() anymore:

    (gdb) python exit(0)
    Python Exception <class 'SystemExit'>: 0
    Error occurred in Python: 0

Use the GDB's own exit command, like it's already done in a couple
places, everywhere. This is the same fix as commit 93a3048dcf45
("tests: Gently exit from GDB when tests complete"), but applied to
more places.
