runtests: add one space to check result more clearly when command nam…

…e is too long

VM case result is long like as following:
guest.test_launcher.sh -v 1 -s 1 -m 1 -d on -t tdx -x TD_BOOT -c "accept_memory=lazy" -p offPASS       0           21.070s

Add one space and make the result more clearly as following:
guest.test_launcher.sh -v 1 -s 1 -m 1 -d on -t tdx -x TD_BOOT -c "accept_memory=lazy" -p off PASS      0           21.000s
