Add deleted libraries to process listing

Add a list of deleted libraries being used by running processes and add them to the processes table:

```
"1055": {
    "user": "root",
    "start_time": "14:25",
    "nice": "0",
    "cpu": "0.0",
    "mem": "0.3",
    "command": "/usr/libexec/postfix/master",
    "deleted_libraries": [
      "/lib64/libgssapi_krb5.so.2.2",
      "/lib64/libk5crypto.so.3.1",
      "/lib64/libkrb5.so.3.3",
      "/lib64/libkrb5support.so.0.1",
      "/lib64/liblber-2.4.so.2.5.6",
      "/lib64/libldap-2.4.so.2.5.6",
      "/lib64/libnspr4.so",
      "/lib64/libplc4.so",
      "/lib64/libplds4.so",
      "/usr/lib64/libcrypto.so.1.0.1e",
      "/usr/lib64/libnss3.so",
      "/usr/lib64/libnssutil3.so",
      "/usr/lib64/libsmime3.so",
      "/usr/lib64/libssl.so.1.0.1e",
      "/usr/lib64/libssl3.so",
      "/usr/lib64/mysql/libmysqlclient.so.16.0.0;53455944"
    ]
  },
```

This can be used to determine if a process may need to be restarted in order to apply security patches provided by an upgraded package (I'm looking at you `libssl`).
