Namcap already depends on pyelftools, which contains an elegant way to
retrieve the soname information directly from libalpm.so (demonstrated
in readelf.py).
Using hardcoded strings means the testsuite periodically breaks (every
time the external pacman project bumps their soname), for no good reason
and at least a few bad ones.
