ZTS: small fix for SEEK_DATA/SEEK_HOLE tests (#16413)

Some libc's like uClibc lag the proper definition of SEEK_DATA and SEEK_HOLE. Since we have only two files in ZTS which use these definitons, let's define them by hand: ``` #ifndef SEEK_DATA #define SEEK_DATA 3 #endif #ifndef SEEK_HOLE #define SEEK_HOLE 4 #endif ``` There should be no failures, because: - FreeBSD has support for SEEK_DATA/SEEK_HOLE since FreeBSD 8 - Linux has it since Linux 3.1 - the libc will submit the parameters unchanged to the kernel Signed-off-by: Tino Reichardt <[email protected]> Reviewed-by: Tony Hutter <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]>
