libxc: remove usage of "daylight" variable

FreeBSD doesn't implement the XSI extension that mandates the presence
of the daylight variable as described in:

http://pubs.opengroup.org/onlinepubs/009696799/functions/tzset.html

So avoid using it for portability reasons. Use tm_isdst instead to
decide if daylight savings time conversions should be used or not.
