  Definition for MREMAP_DONTUNMAP is not present in glibc older than
2.32 thus throwing an undeclared error when running make on mm. Including
linux/mman.h solves the build error for people having older glibc.

Fixes: 0183d777c29a ("selftests: mm: remove duplicate unneeded defines")
Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>
Closes: https://lore.kernel.org/linux-mm/CA+G9fYvV-71XqpCr_jhdDfEtN701fBdG3q+=bafaZiGwUXy_aA@mail.gmail.com/
