[LTP] [PATCH 1/1] sendfile0{2,9}: Remove OFF_T workaround

[Petr Vorel]

Using OFF_T definition to off64_t for 64bit variants seems to be am old
workaround for buggy libc. Nowadays we can rely on off_t to have correct size
(i.e.: 32bit: 4 bytes; 64bit or 32bit with -D_FILE_OFFSET_BITS=64: 8 bytes)

Suggested-by: Cyril Hrubis <chrubis@suse.cz>
Signed-off-by: Petr Vorel <pvorel@suse.cz>

NOTE: -DOFF_T=off64_t is also defined in testcases/kernel/io/disktest
and mentioned in {tst_,}safe_macros.h.

Kind regards,
Petr
