zephyr: Add util to normalize symlinks from lcov
Building a zephyr ztest with zmake (say that 3 times fast) creates many
symlinks, and makes it hard to merge the coverage output. The
util/normalize_symlinks.py tool takes a lcov info file as input and
replaces symlinks with their actual paths in all SF: lines.
BUG=b:183007888
TEST=Ran the commands in the md file.
