    selftests/mm: fix awk usage in charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh that may cause error
    
    [ Upstream commit bbe246f875d064ecfb872fe4f66152e743dfd22d ]
    
    According to the awk manual, the -e option does not need to be specified
    in front of 'program' (unless you need to mix program-file).
    
    The redundant -e option can cause error when users use awk tools other
    than gawk (for example, mawk does not support the -e option).
    
    Error Example:
    awk: not an option: -e
