Revert "sfeed: set TZ=UTC at start, use mktime() not the deprecated timegm()."

Some libc implementations like musl provide a heavy optimized version of timeg()
which mktime() cannot provide. We use -D_BSD_SOURCE anyway (also for strlcpy,
strlcat), so just keep using this for now.

This reverts commit f7c579c3b8e77215d60f1948367221b738823585.
