Public bug reported:
In verbose mode, if files differ in share_files(), dhpython will try to
show a diff of the files. When these files are static libraries, this
raises a UnicodeDecodeError. For example, from a recent numpy build on
arm64[1]:
W: dh_python3 fs:146: Paths differ:
debian/python3-numpy/usr/lib/python3.10/dist-packages/numpy/random/lib/libnpyrandom.a
and
debian/python3-numpy/usr/lib/python3/dist-packages/numpy/random/lib/libnpyrandom.a

There is already logic to skip this diff for .so files, so the same
should be done for .a files.
