Hi,

this is a cleanup work based on discussion:

https://lore.kernel.org/ltp/CAEemH2fwu+LSBrsQh6x6C-QsOLJ5O33xMYHG7wjbiPfN4D=fMw@mail.gmail.com/

I'd like to get it merged before release (TST_ENABLE_DEBUG has not been
released yet, it'd be good to get it fixed before release). We should
mention LTP_NO_CLEANUP in the release notes.

Kind regards,
Petr

Variables which are supposed to be user defined should use LTP_ prefix
instead of TST_ prefix.
