Comment inner workings of sys_[l]lseek

The code doesn't look fully correct to me, but I need to experiment
on actual x32 machine before I start "fixing" things.
For now, add comments, and optimize out one tprints() call...

* file.c (sys_lseek): Rename '_whence' as 'whence'.
Merge printing of ", " into subsequent tprintf.
(sys_lseek32): Likewise.
(sys_llseek): Likewise.
