Allow to install core snap optionally

Browse Source 
Commit 245f7772bdb74 added code to abort the build if a snap wants to
install "core" (the 16.04 runtime). That's great but there are still
some CPC maintained image builds that use snaps based on "core". So
make it possible to continue the build if the "ALLOW_CORE_SNAP" env
variable is set.

(cherry picked from commit 34735684d5208981b2413047f67ee4c363d718d8)
