We can spare a bit of the duplication by definign the function name:

...

#ifdef __TEST_H__
# define TST_SYSCALL_WRAPPER ltp_syscall
#else
# define TST_SYSCALL_WRAPPER tst_syscall
#endif

...
	return (long)TST_SYSCALL_WRAPPER(__NR_fallocate, fd, mode,
				 __LONG_LONG_PAIR((off_t) (offset >> 32),
						  (off_t) offset),
				 __LONG_LONG_PAIR((off_t) (len >> 32),
						  (off_t) len));
