[BUG] salt-ssh 3007.3 broken with transactional-update system

Description
I am running openSUSE microOS (transactional-update) in KVM x86_64 virtual environment.
I also have test salt-ssh configuration including Saltfile, config/master, config/roster, states/top.sls, and states/nginx.sls.

Setup

config/master includes the following module_executors

ssh_minion_opts:
  module_executors:
    - transactional_update
    - direct_call

states/top.sls:

base:
  '*':
    - nginx

states/nginx.sls:

nginx:
  pkg.installed: []

Please be as specific as possible and give set-up details.

• VM KVM x86_64

Steps to Reproduce the behavior

Start with the reproduced salt-ssh command and inspect salt/modules/zypperpkg.py, especially _is_rpm_lock and install, along with the transactional_update module executor configuration. Verify the behavior on the reported openSUSE microOS setup. Done means the nginx state installs the package without the read-only filesystem error.
