Fix GCC 10+ build failure with zstd version 1.2.0 or older.
Extends the configure check for zstd.h to also verify the zstd version,
since gcc requires features that only exist in 1.3.0 and newer. Without
this patch we get a build error for lto-compress.c when using an old zstd
version.

* configure.ac (gcc_cv_header_zstd_h): Check ZSTD_VERISON_NUMBER.
* configure: Regenerated.
