linux-user/host/s390: Add vector instructions to host_signal_write()
The new noexec test fails on s390x with "unexpected SEGV". This test
overwrites code using libc's memcpy(), which uses VSTL instruction.
host_signal_write() does not recognize it, which causes SEGV to be
incorrectly forwarded to the test.
Add all vector instructions that write to memory to
host_signal_write().
Fixes: ab12c95d3f19 ("target/s390x: Make translator stop before the end of a page")
