test: make TEST-86-MULTI-PROFILE-UKI robust against reruns

When qemu reboots instead of shutting down after the last iteration,
the profile is already set to profile2 but the /root/encrypted.raw is
gone so the test fails. Reset the default boot entry at the end of the
test to make it robust against reruns.

Fixes https://github.com/systemd/systemd/issues/39553
