Change Description

In script eos/scripts/eosio_build.sh, line 122, set -i pop error on centos7 and conetos8, so, add OS judge and not use set -i on CentOS, tested can be built without "set -i";
In script eos/scripts/eosio_build_centos.sh, it regard centos version as 7 without judge, and install package which only can be used on centos 7. I add judge and install package which can be used on centos8. centos 7 will still install the original packages.

For .cicd, dockerfile were added both pinned and unpinned. and then the build script to run the pipeline for Centos8.
