The `UNLEAK()` macro has been introduced with 0e5bba53af (add UNLEAK
annotation for reducing leak false positives, 2017-09-08) to help us
reduce the amount of reported memory leaks in cases we don't care about,
e.g. when exiting immediately afterwards. We have since removed all of
its users in favor of freeing the memory and thus don't need the macro
anymore.
Remove it.

- * You can mark a stack variable with UNLEAK(var) to avoid it being
- * reported as a leak by tools like LSAN or valgrind. The argument
- * should generally be the variable itself (not its address and not what
- * it points to). It's safe to use this on pointers which may already
- * have been freed, or on pointers which may still be in use.
- *
- * Use this _only_ for a variable that leaks by going out of scope at
- * program exit (so only from cmd_* functions or their direct helpers).
- * Normal functions, especially those which may be called multiple
- * times, should actually free their memory. This is only meant as
- * an annotation, and does nothing in non-leak-checking builds.
