libcamera: skip auto version generation when building for Chromium OS

Browse source 
Commit b817bcec6b ("libcamera: Auto generate version information")
causes the build to fail in the Chromium OS build environment, because
git update-index tries to take a lock (ie. write) in the git repo that
is outside of the build directory.

The solution is to simply skip git update-index if we are building in
the Chromium OS build environment, and this decision is made if the
build directory is not a subdirectory of the source directory.
