check-whitespace: detect if no base_commit is provided
The 'check-whitespace' CI script exits gracefully if no base commit is
provided or if an invalid revision is provided. This is not good because
if a particular CI provides an incorrect base_commit, it would fail
successfully.
This is exactly the case with the GitLab CI. The CI is using the
"$CI_MERGE_REQUEST_TARGET_BRANCH_SHA" variable to get the base commit
SHA, but variable is only defined for _merged_ pipelines. So it is empty
for regular pipelines [1]. This should've failed the check-whitespace
job.
Let's fallback to 'CI_MERGE_REQUEST_DIFF_BASE_SHA' if
"CI_MERGE_REQUEST_TARGET_BRANCH_SHA" isn't available in GitLab CI,
similar to the previous commit. Let's also add a check for incorrect
base_commit in the 'check-whitespace.sh' script. While here, fix a small
typo too.
