Subject: [PATCH v2] selftests/mm: include strings.h for ffsl

Got a compilation error on Android for ffsl after 91b80cc5b39f
("selftests: mm: fix map_hugetlb failure on 64K page size systems")
included vm_util.h.

Fixes: af605d26a8f2 ("selftests/mm: merge util.h into vm_util.h")
Signed-off-by: Edward Liaw <edliaw@...gle.com>
---
v2: s/import/include and clarified that compilation error was on Android
