    build: remove redundant shebang from apk lifecycle scripts
    
    Due to the way apk lifecycle scripts are defined, they might end up with
    multiple shebangs. Remove them.
    
    Before:
    
      post-upgrade: |
        #!/bin/sh
        export PKG_UPGRADE=1
        #!/bin/sh
        [ "${IPKG_NO_SCRIPT}" = "1" ] && exit 0
        [ -s ${IPKG_INSTROOT}/lib/functions.sh ] || exit 0
        . ${IPKG_INSTROOT}/lib/functions.sh
        export root="${IPKG_INSTROOT}"
        export pkgname="adblock-fast"
        add_group_and_user
        default_postinst
        #!/bin/sh
        # check if we are on real system
        if [ -z "${IPKG_INSTROOT}" ]; then
            /etc/init.d/adblock-fast enable
        fi
        exit 0
    
    After:
    
      post-upgrade: |
        #!/bin/sh
        export PKG_UPGRADE=1
        [ "${IPKG_NO_SCRIPT}" = "1" ] && exit 0
        [ -s ${IPKG_INSTROOT}/lib/functions.sh ] || exit 0
        . ${IPKG_INSTROOT}/lib/functions.sh
        export root="${IPKG_INSTROOT}"
        export pkgname="adblock-fast"
        add_group_and_user
        default_postinst
        # check if we are on real system
        if [ -z "${IPKG_INSTROOT}" ]; then
            /etc/init.d/adblock-fast enable
        fi
        exit 0
