Remove requirement to set _BSD_EXTENSION when including sys/time.h, it
is now part of the XSI standard and many apps require it.

Seems that the timezone part didn't make it into the standard and
seems to be deprecated, so I left it inside a _BSD_EXTENSION ifdef in
case any old code depends on it (I have't found any).
