[Gluster-infra] Fix bug-id extraction in compare-bug-version-and-git-branch

The bug-id extraction method in the compare-bug-version-and-git-branch
was buggy. Which lead to some valid changes being marked as invalid.

The following snippet was used
BUG=$(git show --name-only --format=email | grep -i '^BUG: ' | cut -f2
-d ' ' | tail -1)

The problem is with the usage of `cut`, which as used here cannot
handle multiple whitespace between 'BUG: ' and the ID.

I'll replac `cut` with `awk` which should work better. The snippet now
looks like
BUG=$(git show --name-only --format=email | awk '{IGNORECASE=1}
/^BUG:/{print $2}' | tail -1)
This should work much better.
