Fix a TypeError: Object of type 'bytes' is not JSON serializable

On ArchLinux, using a python3 virtualenv as described in the README, asking a json output for a static analysis crash with a type error.

A txt output show the following:

…
- App libraries: 1
    - b'com.sec.android.app.multiwindow'
…

Thus, I just convert the get_libraries output from an array of bytes to an array of string.

Dexdump binary used is from the android SDK v. 27.0.3

The crash stack trace is:

$ python exodus_analyze.py -j ~/latest.apk
