configure: add <sys/timex.h> for clock_adjtime on musl (#2085)

clan · web-flow · commit a78d690da54f · 2025-01-14T08:47:54.000+08:00
for glibc, if _GNU_SOURCE is defined, &lt;time.h&gt; will include &lt;sys/timex.h&gt;
but not for musl, so add "#include &lt;sys/timex.h&gt;"

although `man clock_adjtime` said "#include &lt;sys/timex.h&gt;", but it won't
work for glibc w/o "#include &lt;time.h&gt;", I don't known why yet.

PS it seems clock_adjtime is used nowhere?
