meson: Check GNU sed's availability

Browse Source 
As explained in the comment in build-aux/Makefile.in, the
version of sed included in the FreeBSD base system is not GNU
sed, which our syntax-check rules expect; as a result, many
checks will fail with

  gmake: gsed: No such file or directory
  /bin/sh: gsed: not found

Similarly to what we're already doing with GNU make and GNU
grep, look for GNU sed during the configuration step and fail
early if it's not available.
