    linux: Get rid of 000-keep_initrafs_the_default.patch
    
    With that patch in place for initramfs no additional options are
    reported for "/" partition. What's really important is missing
    info about sizes. Which in its turn makes opkg think that there's
    no space on "/" partition to install software.
    
    I understand that's a sort of corner-case, people rarely install
    packages on ramfs but anyways why not?
    
    Just in case that's what I see with the patch:
    ---------------------->8--------------------
    root at lede:/# cat /proc/mounts
    rootfs / rootfs rw 0 0
    proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
    sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
    tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
    tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
    devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
    debugfs /sys/kernel/debug debugfs rw,noatime 0 0
    ---------------------->8--------------------
    
    And without:
    ---------------------->8--------------------
    root at lede:/# cat /proc/mounts
    rootfs / rootfs rw,size=256168k,nr_inodes=32021 0 0
    proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
    sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
    tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
    tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
    devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
    debugfs /sys/kernel/debug debugfs rw,noatime 0 0
    ---------------------->8--------------------
    
    Note how different is entry for rootfs.
    
    And given there's no known rationale for that patch we're
    getting rid of it.
