[OS-BUILD PATCH 7/20] [redhat] new_release.sh: Fix syntax flagged by shellcheck

[GitLab Bridge on behalf of bcrocker <cki-gitlab@xxxxxxxxxx>]

From: Ben Crocker <bcrocker@xxxxxxxxxx>

SC2007: Use $((..)) instead of deprecated $[..]
SC2086: Double quote to prevent globbing and word splitting.
SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined.
