Re-enable no-unused-lamda-capture and no-format-trucation

These were disabled as a quick fix for microsoft#778 in microsoft#779.

* no-format-truncation was properly fixed in microsoft#787
* no-unused-lamda-capture was worked around in microsoft#732
* gaurds for gcc 5.4 were added in microsoft#849 but with microsoft#787 aren't needed
