testsuite: Fix up strlenopt-80.c on powerpc [PR99636]

Similar issue as in strlenopt-73.c, various spots in this test rely
on MOVE_MAX >= 8, this time it uses a target selector to pick up a couple
of targets, and all of them but powerpc 32-bit satisfy it, but powerpc
32-bit have MOVE_MAX just 4.

    The optimization is only implemented for MEM_REF stores and other
    targets than those below may not transform the memcpy call into
    such a store.
