Steffen Eiden 3cc0b4cdea pvattest/tools: remove xxd dependency from scripts 
xxd has vim-common as a dependency. We can avoid that by using od
instead which is from coreutils.

While at it, add the require_command function from the
pvattest-info script to the pvextract-hdr script and use it.

Steffen Eiden 1ffd767977 pvattest/tools: Add script to display config UID and additional data 
Although the previous patch enables pvattest to display the
config UID this script enables the user to extract the config UID of
the SE-guest and the additional data if specified. This allows users of
pvattest v2.22.0 to view the config UID without examining binary blobs.

$ ./pvattest-info attresult.bin
Config UID:
1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a
Additional Data:
1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b1b
