tests/tcg/s390x: Test modifying an EXECUTE target

QEMU correctly implements the tracking of EXECUTE target modifications
by storing the instruction text in env->ex_value and tb->cs_base, the
latter of which is used for lookups.

Still, EXECUTE is a tricky corner of the s390x emulation, which can
benefit from having a regression test.
