util/chromeos/gen_test_hwid.sh: Replace usage of hexdump

Hexdump command is not available in coreboot-sdk. Replace it with
equivalent implementation using commands that are present in the
container.

TEST=Passed "VP46XX" as prefix variable and it produced the same
crc32 result before and after the change.
