- Improvements
        - Link to libcrypto rather than requiring openssl

        - Print a better error message when kernel doesn't support module unload

        - Use PKCS#7 instead of CMS for parsing module signature to be
          compatible with LibreSSL and OpenSSL < 1.1.0

        - Teach modinfo to parse modules.builtin.modinfo. When using
Linux kernel
          >= v5.2-rc1 it's possible to get module information from
this new file. Now
          modinfo is able to show it instead of an error message that
the module is
          built-in:

          Before:
          $ modinfo ext4
          modinfo: ERROR: Module ext4 not found.

          After:
          $ modinfo ext4
          name:           ext4
          filename:       (builtin)
          softdep:        pre: crc32c

- Bug fixes
        - Do not link python bindings with libpython to be compatible with
          python3.8

        - Fix module removal with `modprobe -r` when a dependency is built-in.
          Now it properly ignores them and proceed with removal of other
          dependencies

        - Fix propagation of return code from install/remove commands to the
          the probe function. The return values of
kmod_module_probe_insert_module()
          have very specific meanings, do not confuse the caller by return codes
          from system()

        - Fix softdep config parsing leading to buffer overflow
