allocator: remove ENABLE_MEMORY_TASK_PROFILER and use only USE_ALLOCATOR_SHIM

After the recent cleanup of crrev.com/2907563002, the flag
ENABLE_MEMORY_TASK_PROFILER became redundant and now is just
matching 1:1 USE_ALLOCATOR_SHIM. Use that instead.
No intended behavior change.
Also fix mistake of using defined(X) instead
of BUILDFLAG(X).

BUG=550886
