BUG/MINOR: pools: restore detection of built-in allocator

The runtime detection of the default memory allocator was broken by
Commit d8a97d8f6 ("BUG/MINOR: illegal use of the malloc_trim() function
if jemalloc is used") due to a misunderstanding of its role. The purpose
is not to detect whether we're on non-jemalloc but whether or not the
allocator was changed from the one we booted with, in which case we must
be extra cautious and absolutely refrain from calling malloc_trim() and
its friends.

This was done only to drop the message saying that malloc_trim() is
supported, which will be totally removed in another commit, and could
possibly be removed even in older versions if this patch would get
backported since in the end it provides limited value.
