Summary:
Before this fix the FileSpec::GetPath() returned string which might be without '\0' at the end.
It could have happened if the size of buffer for path was less than actual path.
Test case:
```
FileSpec test("/path/to/file", false);
char buf[]="!!!!!!";
test.GetPath(buf, 3);
```
Before fix:
```
233 FileSpec test("/path/to/file", false);
234 char buf[]="!!!!!!";
235 test.GetPath(buf, 3);
236
-> 237 if (core_file)
238 {
239 if (!core_file.Exists())
240 {
(lldb) print buf
(char [7]) $0 = "/pa!!!"
```
After fix:
```
233 FileSpec test("/path/to/file", false);
234 char buf[]="!!!!!!";
235 test.GetPath(buf, 3);
236
-> 237 if (core_file)
238 {
239 if (!core_file.Exists())
240 {
(lldb) print buf
(char [7]) $0 = "/p"
```
