mtce daemon_get_file_str returns first word not full string

[Eric MacDonald]

The common daemon_get_file_str returns the first word of the first line not the entire first line of the specified file as was intended.

Want to use this function in another update but don`t want this to be tied to that update.

Severity:
--------
Minor since the only place its used has only a single word in the file.

Steps to Reproduce:
------------------
Call function with filename parameter referring to a file containing a space delimited sentence in the first line.

Expected Behavior
------------------
returns string with the full first line

Actual Behavior
----------------
Returns only the first word in the line

Reproducibility
---------------
100%

System Configuration
--------------------
Any

    Make daemon_get_file_str return first line in specified file

    The current implementation will return only the first
    group of characters up to the first space from the first
    line of the specified file.

    This function was intended to return the entire first line.
