[LTP] [PATCH V2 06/32] sendfile: Use off64_t instead of __off64_t

[Khem Raj]

__off64_t is specific to glibc where as off64_t is widely available
Add _GNU_SOURCE for off64_t defines from sys/types.h
Fixes
<command-line>:0:7: error: unknown type name 'off64_t'
sendfile02.c:97:18: note: in expansion of macro 'OFF_T'
