patch 8.2.2058: using mkview/loadview changes the jumplist

Commit: https://github.com/vim/vim/commit/3482be6a33c3a00fe1e8e604310ad3034f593045

    patch 8.2.2058: using mkview/loadview changes the jumplist

    Problem:    Using mkview/loadview changes the jumplist.
    Solution:   Use ":keepjumps".  Don't let ":badd" or ":balt" change the
                jumplist. (closes #7371)
