librbd: use custom allocator for aligned boost::lockfree::queue

If tcmalloc is in-use as the allocator and its version is less than 2.6.2,
it might be missing support for 'aligned_alloc'. This can result in the
glibc version of 'aligned_alloc' being used to allocate memory that is
then freed by tcmalloc -- resulting in a crash.
