[LTP] [PATCH 2/4] checkpoint: add TST_CHECKPOINT_INIT() for new library headers

[Sandeep Patil <sspatil@google.com>]

The macro was missing unlike the new library equivalents of old
TST_SAFE_CHECKPOINT_{WAIT/WAKE} macros. So, add it, so it can be used
immediately in mm/mallocstress test conversion to checkpoint API.
