install-deps.sh: remove existing ceph-libboost of different version
we install different versions of precompiled ceph-libboost packages
for different branches when building and testing them on ubuntu test
nodes. for instance,
- nautilus: v1.72
- octopus, pacific: v1.73
they share the same set of test nodes. and these ceph-libboost packages
conflict with each other, because they install files to the same places.
in order to avoid the confliction, we should uninstall existing packages
before installing a different version of ceph-libboost packages.
ceph-libboost${version}-dev is a package providing the shared headers of
boost library, so, in this change we check if it is installed before
returning or removing the existing packages.
