qemu-config: use pkg_postinst to generate the proper shutdown.desktop

[YOCTO #1507]

We need to remove the file qemuarm/shutdown.desktop, or else, on qemuarm,
due to the PACKAGE_ARCH overriding from all to qemuarm in base.bbclass,
the generated deb file will be stored at
tmp/deploy/deb/qemuarm/qemu-config_1.0-r21_allarch.deb rather than
tmp/deploy/deb/all/qemu-config_1.0-r21_all.deb, and the package qemu-config
won't be installable -- task-base finally rdepends on qemu-config, so we get
the do_rootfs failure:

The following packages have unmet dependencies:
|   task-base-extended: Depends: task-base but it is not going to be installed
| E: Broken packages

There is also a generic shutdown.desktop, we can keep it and use a proper
pkg_postinst to cope with the case of qemuarm.
