setup: Apply targeted test filter to all arches
Move the --targeted=yes
option to the beginning of kpet run test list
command line, so it has effect on all architectures.
This is necessary due to a recent change making the --triggered/--targeted
options per-execution: kpet@feba40ff
Without this only the last architecture's execution would have tests limited to targeted-only, and all the previous ones would list all tests.
