75bdcb7 Write to `/var/lib/kdump` if $KDUMP_BOOTDIR not writable

    Write to `/var/lib/kdump` if $KDUMP_BOOTDIR not writable
    
    The `/boot` directory on some operating systems might be read-only.
    If we cannot write to `$KDUMP_BOOTDIR` when generating the kdump
    initrd, attempt to place the generated initrd at `/var/lib/kdump`
    instead.
