[OE-core] [PATCH 3/3] oeqa/runtime/cases/rpm.py: workaround race condition

[Chen Qi]

With the recent change in new systemd version, it's possible that
a user is deleted before stopping user-runtime-dir at xxx.service.
See link below.

  https://github.com/systemd/systemd/issues/9541

Workaround this issue by delay for 1 second before deleting user.
