Fix warning about conflicting lseek/lseek64 prototypes

Clang rightfully complains about conflicting prototypes, as both lseek() variants are redefined: syscall.c:394:10: warning: a function declaration without a prototype is deprecated in all versions of C and is treated as a zero-parameter prototype in C2x, conflicting with a previous declaration [-Wdeprecated-non-prototype] off64_t lseek64(); ^ /usr/include/unistd.h:350:18: note: conflicting prototype is here extern __off64_t lseek64 (int __fd, __off64_t __offset, int __whence) ^ 1 warning generated. The point of the #ifdef is to build for the configured OFF_T; there is no reason to redefine lseek/lseek64, which should have been found via configure.
