qemu: bump to version 5.0.0

The slirp patch was included in this QEMU release

CXX_DEPENDS is now added for all host components otherwise we get
errors like the following

  Package qemu-img is missing dependencies for the following libraries:
  libuClibc++.so.0
  Package qemu-nbd is missing dependencies for the following libraries:
  libuClibc++.so.0

--disable-bluez was removed from configure args because upstream
deprecated bluetooth subsystem since qemu v3.1 and remove the code in
commit 1d4ffe8dc77c ("Remove the core bluetooth code")

-Subject: [PATCH] ip_reass: Fix use after free
-
-Using ip_deq after m_free might read pointers from an allocation reuse.
-
-This would be difficult to exploit, but that is still related with
-CVE-2019-14378 which generates fragmented IP packets that would trigger this
-issue and at least produce a DoS.
