Title: Do not set IFS to the wrong value

The correct way to reset it to the default would be `IFS=$' \t\n'`, but
there's no reason to assume a wrong setting here, in fact, nothing this
script does should depend on an IFS setting, so let's just drop this
line altogether.

Tested:
- Ran "release/build-release.sh " before and after this
change. Compared the two trees for differences, only difference was
the SHA1 in output/release/master-release/src/saltbase/pillar/common.sls
