Steffen Eiden 96897ee32e pvattest/tools: fix endianness in tools 
`od` in contrast to `xxd` uses the system endianness for displying the
hexdump by default which leads to invalid results on little endian
systems.
Use the `--endian=big` option to fix the endianness problem.

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.
