    Patch state reporting bugfix

    This commit fixes the sw-patch reporting bug.

    Bug description: Applied patches go to a Partial-Applied state
    after applying a new reboot-required patch, until the system reboots.

    Please note that this bug only happens when applying a new patch,
    when removing patches the previously applied patches don't have
    their state changed.

    sw-patch query result before applying a new patch:

                 Patch ID RR Release Patch State
        =========================== == ======= ===========
        PATCH_0001 Y 9.0 Applied
        PATCH_0002 Y 9.0 Applied
        PATCH_0003 Y 9.0 Applied
        PATCH_0004 Y 9.0 Applied
        PATCH_0005 Y 9.0 Available

    Then after applying the latest patch, previously applied patches
    go to partial-applied, as follows:

                 Patch ID RR Release Patch State
        =========================== == ======= =============
        PATCH_0001 Y 9.0 Partial-Apply
        PATCH_0002 Y 9.0 Partial-Apply
        PATCH_0003 Y 9.0 Partial-Apply
        PATCH_0004 Y 9.0 Applied
        PATCH_0005 Y 9.0 Partial-Apply

    This happens because the previously applied patches commit
    doesn't match the latest_sysroot_commit, but the latest applied patch
    (in our example PATCH_0004) do have their commit matching, so we need
    to mark their dependent patches as Applied.

    Test Plan:

    PASS: For in-service patches (non reboot-required) the issues doesn't happen and the bugfix in place it has the same behavior.

    PASS: Python code for patch_controler.py unit tests pass and a
    a new test case was created to cover this condition

    After this bugfix, using a virtual machine with patched code, the patch reports are the following:

                 Patch ID RR Release Patch State
        =========================== == ======= =============
        PATCH_0001 Y 9.0 Applied
        PATCH_0002 Y 9.0 Applied
        PATCH_0003 Y 9.0 Applied
        PATCH_0004 Y 9.0 Applied
        PATCH_0005 Y 9.0 Partial-Apply
