<rdar://problem/12827031>

Fix the OptionValueFileSpec option value to correctly get the file path when trailing spaces are on the path. The "settings set" command uses the OptionValueFileSpec class to set file paths and if extra spaces are at the end it will include those in the paths. Now we chop up the value send to to OptionValueFileSpec::SetValueFromCString(...) function with "lldb_private::Args" and give an appropriate error if more than one path is used. It also allows for quotes to be used when specifying the path.
