linux-user does not check PROT_EXEC

At no point do we actually verify that a page is PROT_EXEC before translating.  All we end up verifying is that the page is readable.  Not the same thing, obviously.

The following test case should work for any architecture, though I've only validated it for x86_64 and aarch64.



It turns out we can't fix this without also fixing
our implementation of signal trampolines.
