build-unit-test-docker: use alternative for cpp
We added an 'alternative' for GCC but not for the preprocessor.
It seems potentially problematic to use an older preprocessor,
which came with the distro, but a newer compiler, so set the
preprocessor as the same version as GCC. The preprocessor is
required to be installed as a separate alternative and not with
the "--slave" option.
