Restrict legacy patch check to stx-8 or less

During USM upgrade to stx-10, when the second controller
is upgraded, the active controller legacy patch controller
change from-release Applied patches to Partial-Apply state,
because the sysroot ostree commit-id changes on the second
controller and doesn't match the previous patches commits
anymore.

This commit restricts legacy patch API checks/changes to
hosts running stx-8 or less, where legacy patch API is valid.
On post stx-8 releases USM is the new patch API.

Test Plan
PASS: AIO-SX stx-8 -> stx-10 upgrade,
      verify patch state is consistent
PASS: AIO-SX stx-10 -> stx-8 rollback,
      verify patch state is consistent
PASS: STD, same as previous TCs
