[test][llvm-dwarfdump] Normalise contents and checks for line tables

[jhenderson]

Summary

The line tables in debug_line_malformed.s had contents that varied more than was necessary for the testing, making it harder to follow what was important. This patch normalises them so that they all share more-or-less the same body. Additionally, it makes the testing for what was printed more consistent, to show that the right parts of the line table prologue and body are/are not parsed and printed.

Depends on D71753.
