[PATCH qemu 2/2] d/{control,rules}: drop libsdl dependency

[Fiona Ebner <f.ebner@proxmox.com>]

The --disable-sdl flag is used during build, but the libsdl1.2-dev
build dependency was still present in d/control. That dependency
implicitly pulled in others. Drop the libsdl build dependency and be
explicit about the dependencies that were previously pulled in and the
features they auto-enabled, namely:
* libasound2-dev for CONFIG_AUDIO_ALSA
* libdrm-dev for HAVE_DRM_H (this is only used for linux-user, so could
  be dropped with a major release if desired)
* libglib2.0-dev (glib is widely used in the QEMU source code)
* libpulse-dev for CONFIG_AUDIO_PA
* libsndio-dev for CONFIG_AUDIO_SNDIO
* libxkbcommon-dev for qemu-keymap

The non-alsa audio libraries could be dropped with a major release if
desired. It seems that enabling support might have been done
unintentionally, because in debian/rules, --audio-drv-list="alsa" is
used. However, the backends are still auto-enabled when the libraries
are found, this list seems to be only used for the priorities for the
default audio backend.
