[Spice-devel] [PATCH spice-gtk v2] build-sys: Make git-version-gen work again with Meson

[Frediano Ziglio]

d0cbd9618f0b removed the ability to use git-version-gen to generate
proper version string.
Generate .tarball-version file in the distribution file to allow
building from tarball.
Do not use MESON_SOURCE_ROOT when calling git-version-gen command as
this won't be expanded.
Change directory in git-version-gen script to allow the script to be
called from a different directory.
