        fix broken extra_bins when installing multiple binaries
    
        When there more than one binaries, quoting "$val" would make
        dracut-install treat multiple binaries as one binary. Take
        "extra_bins /usr/sbin/ping /usr/sbin/ip" as an example, the
        following error would occur when building initrd,
    
        dracut-install: ERROR: installing '/usr/sbin/ping /usr/sbin/ip'
        dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.ODrioZ/initramfs -a /usr/sbin/ping /usr/sbin/ip
    
        Fix it by not quoting the variable and bypassing SC2086 shellcheck.
