[RFC PATCH] scripts/qemu-version.sh: Always describe tag version

[Philippe Mathieu-Daudé]

I'm not sure why sometime I get this error:

  $ make
  Generating qemu-version.h with a meson_exe.py custom command
  fatal: No tags can describe 'dc9f825f99eb5dc82f127e6c95fbe3a503e11346'.
  Try --always, or create some tags.

While to --always option is not clear in GIT-DESCRIBE(1):

   --always
       Show uniquely abbreviated commit object as fallback.

using it works and fix my builds:

  $ git describe --match 'v*' --dirty --always
  dc9f825f99e-dirty
