Always check return value of strftime().
		
strftime() returns 0 and leaves the contents of the output buffer
unspecified if the output buffer is not big enough.  Thus, one should
check strftime()'s return value.  Until now, OVS has had a few invocations
of strftime() that did not check the return value.  This commit fixes
those.  I believe that the buffers were always large enough in each case,
but it's better to be safe.
