Disable fork detection test on qemu.

Its madvise() is still broken today (just in a different way from the
past - it still returns success on invalid advice flags, which means
that we cannot distinguish pre- and post-MADV_WIPEONFORK implementation
versions of qemu.

I also thought of another way - namely, checking MADV_WIPEONFORK on a
MAP_SHARED mapping - which qemu correctly refuses, but FreeBSD's
linux.ko does not. So given it's inaccurate anyway, let's keep the
current detection and behaviour as is, namely, that we always draw
entropy when needing random data when on qemu.
