tools/mm/thp_swap_allocator_test: fix small folio alignment
Use ALIGNMENT_SMALLFOLIO instead of ALIGNMENT_MTHP when allocating small
folios to ensure correct memory alignment for the test case.
Before: test allocates small folios with 64KB alignment
(ALIGNMENT_MTHP) when only 4KB alignment (ALIGNMENT_SMALLFOLIO) is
needed. This wastes address space and may cause allocation failures on
systems with fragmented memory.
Worst-case impact: this only affects thp_swap_allocator_test tool
behavior.
