Nico Pache 30b651c8bc selftests: mm: add s390 to ARCH check 
commit 0518dbe97f ("selftests/mm: fix cross compilation with LLVM")
changed the env variable for the architecture from MACHINE to ARCH.

This is preventing 3 required TEST_GEN_FILES from being included when
cross compiling s390x and errors when trying to run the test suite.  This
is due to the ARCH variable already being set and the arch folder name
being s390.

Add "s390" to the filtered list to cover this case and have the 3 files
included in the build.

# In other words, "make $SOME_TEST" is supposed to fail to build at all,
