Subject: [PATCH] selftests/mm: switch to bash from sh

Running charge_reserved_hugetlb.sh generates errors if sh is set to
dash:

/charge_reserved_hugetlb.sh: 9: [[: not found
/charge_reserved_hugetlb.sh: 19: [[: not found
/charge_reserved_hugetlb.sh: 27: [[: not found
/charge_reserved_hugetlb.sh: 37: [[: not found
/charge_reserved_hugetlb.sh: 45: Syntax error: "(" unexpected

Switch to using /bin/bash instead of /bin/sh. Make the switch for
write_hugetlb_memory.sh as well which is called from
charge_reserved_hugetlb.sh.
