package/qemu: bump to version 7.0.0

Remove upstream patch 0002-build-disable-fcf-protection-on-march-486-m16.patch

Handle new or removed configure options:
- disable dbus-display
- remove libxml2 configure option

Support for for ARMv4 and ARMv5 hosts has been dropped, Qemu target
package needs at least ARMv6. The architecture test is done at runtime,
so qemu package for ARMv4 or ARMv5 target would build but will error
out at runtime:
https://git.qemu.org/?p=qemu.git;a=commitdiff;h=01dfc0ed7f2c5f8dbab65f31228a2888c7b85a07

See:
https://wiki.qemu.org/ChangeLog/7.0

Runtime tested in gitlab:
https://gitlab.com/kubu93/buildroot/-/pipelines/520991787

Add a new patch fixing the build with seccomp support enabled.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some of the roms build with -march=i486 -m16 which is incompatible
-with -fcf-protection. That in turn is can be set by default, for
-example in Ubuntu [1].
-That causes:
- cc1: error: ‘-fcf-protection’ is not compatible with this target
-
-This won't work on -march=i486 -m16 and no matter if set or not we can
-override it to "none" if the option is known to the compiler to be
-able to build reliably.
-
-Fixes: https://gitlab.com/qemu-project/qemu/-/issues/889
