Contrary to documentation, LoaderFeatures efi variable is 96bit, not 64bit

This looks to me a straight forward github issue. I am not sure where, at 
github, it should be filed.

Quoting https://systemd.io/BOOT_LOADER_INTERFACE/ , with lines break for 
readability

    The EFI variable LoaderFeatures contains a 64bit unsigned integer with 
    a number of flags bits that are set by the boot loader and passed to 
    the OS and indicate the features the boot loader supports. Specifically, 
    the following bits are defined:

      *  1 >> 0 -> The bbot loadere honours LoaderConfigTimeout when set
      *  1 >> 1 -> ...
      *  ...

Here,

    $ od -t x1 /sys/firmware/efi/efivars/LoaderFeatures-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f
    0000000 06 00 00 00 ff 07 00 00 00 00 00 00
    0000014

Which is 14(octal)*8 = 96bit. As a result, it could be the shifting from 
the quote above, 1 >> 0, 1 >> 1, and so on, are also wrong. And perhaps 
it worth adding to the documentation that 

    $ bootctl status

presents those defined bits, as well as other information, in a readable 
form.
