[PATCH v5 10/29] CI: move p4 and git-lfs variables to ci/install-dependencies.sh

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Move the declaration of variables that are only used by the
"ubuntu-latest" block in "ci/install-dependencies.sh" there from
"ci/lib.sh".

This makes the code easier to follow, and changes "ci/lib.sh" to a
library that only exports CI variables for general use, we didn't need
to export these $P4_PATH and $GIT_LFS_PATH variables.
