build: Preserve upstream git versioning using meson dist
When distributions build and package libcamera libraries, they may not
necessarily run the build in the upstream source tree. In these cases, the git
SHA1 versioning information will be lost.
This change addresses that problem by requiring package managers to run
'meson dist' to create a tarball of the source files and build from there.
On runing 'meson dist', the utils/run-dist.sh script will create a
.tarball-version file in the release tarball with the version string generated
from the existing utils/gen-version.sh script.
The utils/gen-version.sh script has been updated to check for the presence of
this .tarball-version file and read the version string from it instead of
creating one.
