[PATCH:xts 02/16] xts5: Fix missing unistd.h include for unlink.

[Cyril Brulebois]

This fixes an implicit declaration:
|   CC     checkarea.lo
| checkarea.c:296:2: warning: implicit declaration of function 'unlink' is invalid in C99 [-Wimplicit-function-declaration]
|         unlink(name);
|         ^
