[issue46956] TextIOWrapper.seek silently wraps around on very large offsets

New submission from László Vaskó : `f.seek()` method may silently wrap around at offsets greater than `1 << 64` (on AMD64) but return the original seek offset: $ strace -e lseek python3 [...] bunch of strace output >>> f = open("/tmp/whatever", "w") [...] bunh of strace output
