Always enable PIE

PIE is currently enabled for qemu-kvm builds, and disabled for
qemu-user-static builds.

--disable-pie is causing https://bugzilla.redhat.com/show_bug.cgi?id=2256916

This commit ensures --enable-pie is used for both qemu-kvm and
qemu-user-static.

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=2256916
