dbus-uuidgen: Enable stack memory protection

Browse source 
Use "return" instead of "exit()" at the end of the main() function to
enable runtime stack overflow checks.

Using "return" allows the program to exit normally from main(), letting
the compiler perform necessary cleanup operations, including stack
canary verification.

When using "exit()" at the end of main(), the __stack_chk_fail function
is not invoked.

$ objdump -T ./util/.libs/mtp-hotplug | grep __stack_chk_fail
(This returns empty.)
