Update dynamic location random user agent list

[aancw]

Hi there,

While testing your program, i'm getting error for random user agent mode because you are using static file location, when installing this program with python setup.py install it get binary alias as VhostScan pointing to /usr/lib/python3.6/site-packages/VHostScan-1.21-py3.6.egg/VHostScan/VHostScan.py but your function still use static location

 with open('./lib/ua-random-list.txt') as f:

Error

[>] Random User-Agent flag set.
Traceback (most recent call last):
  File "/usr/bin/VHostScan", line 11, in <module>
    load_entry_point('VHostScan==1.21', 'console_scripts', 'VHostScan')()
  File "/usr/lib/python3.6/site-packages/VHostScan-1.21-py3.6.egg/VHostScan/VHostScan.py", line 54, in main
    user_agents = load_random_user_agents()
  File "/usr/lib/python3.6/site-packages/VHostScan-1.21-py3.6.egg/VHostScan/lib/helpers/file_helper.py", line 65, in load_random_user_agents
    with open('./lib/ua-random-list.txt') as f:
FileNotFoundError: [Errno 2] No such file or directory: './lib/ua-random-list.txt'

So, i've added dynamic file location as you used before at wordlist_helper.py and change readlines to read function, so i can use splitlines() for fixing this issue:

raise ValueError('Invalid header value %r' % (values[i],))
ValueError: Invalid header value b'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36\n'

If you don't mind, i can implementing fake/random user agent function to this project, as you can see in my project: https://github.com/aancw/Belati/blob/master/plugins/user_agents.py

Thanks!
