Subject: [PATCH] ZTS: small fix for SEEK_DATA/SEEK_HOLE tests

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
