[build-support] fix on enable_devtoolset_inner.sh, take two

Prior to this fix, when configuring a build via cmake as described at
https://kudu.apache.org/docs/installation.html#build_from_source,
the following error was output (at least by bash 4.1.2):

  build-support/enable_devtoolset_inner.sh: line 28: [: too many arguments

This is a follow-up to 719418a60235a5155efe95c37e9fc6e319f41e0c.
