    LUKS: make /usr writable

    Since systemd commit ffc1ec73b3 ("pid1: add ProtectSystem= as system-wide
    configuration, and default it to true in the initrd"), systemd makes
    /usr read-only by default and it will cause dracut to not wait for the
    LUKS-encrypted devices to be unlocked,

        dracut-cmdline[296]: mv: inter-device move failed: '/tmp/294-daemon-reload.sh' to '/lib/dracut/hooks/initqueue/daemon-reload.sh'; unable to remove target: Read-only file syste

        dracut-cmdline[294]: /sbin/initqueue: line 71: /lib/dracut/hooks/initqueue/work: Read-only file system
        dracut-cmdline[221]: /lib/dracut-dev-lib.sh: line 118: /lib/dracut/hooks/initqueue/finished/devexists-\x2fdev\x2fmyvg\x2fluks_lv.sh: Read-only file system
        dracut-cmdline[221]: /lib/dracut-dev-lib.sh: line 103: /lib/dracut/hooks/emergency/80-\x2fdev\x2fmyvg\x2fluks_lv.sh: Read-only file system

    Fix the above issue by making /usr writable.
