[Plugin] Fix string decoding for debug log output

In add_string_as_file and _collect_strings, the first line of each
string is printed to debug log, however there is a bug in
_collect_strings that tries to decode the first line of '...'
instead of the actual string; this causes a error like:

  File "/usr/share/sosreport/sos/sosreport.py", line 1300, in collect
    plug.collect()
  File "/usr/share/sosreport/sos/plugins/__init__.py", line 877, in collect
    self._collect_strings()
  File "/usr/share/sosreport/sos/plugins/__init__.py", line 860, in _collect_strings
    (content.splitlines()[0]).decode('utf8', 'ignore'))
AttributeError: 'str' object has no attribute 'decode'

This simplifies the (string or bytearray)-to-first-line-string of both
functions, which also fixes the bug using the wrong variable to decode.
