Change back aliceHLTWrapper executable name

[dstocco]

In commit 3dc9c2e the aliceHLTWrapperApp executable was changed into aliceHLTWrapper.
However, this causes issues in non-case sensitive systems such as Mac OS X. Indeed, an aliceHLTWrapper.dir is created by cmake...and the system does not distinguish it from the aliceHLTwrapper.dir (notice the lower case for w) which comes from the Utilities/aliceHLTwrapper directory.
Switching back to the old name for the executable solves the issue

I wasn't very happy about the previous change to aliceHLTWrapperApp since this broke a couple of other things. So I changed it back, not being aware of this problem on Mac OS. The change was hidden in a huge commit, so I could not understand the real reason.

I suggest to close this PR, I'm going to make a PR with consistent naming of the executables of the module.

@ktf @dberzano can the CI also be run on a mac os system? That would have detected the problem before the merge.

Shouldn't we rename / move / refactor Utilities/aliceHLTwrapper instead?

Hi @matthiasrichter ,
yes, sure: if you have a better idea on how to solve the issue, please go ahead.
I'm closing the pull request in the meanwhile.

Cheers,
Diego
