Feature #8671: support SEEK_DATA and SEEK_HOLE
https://bugs.ruby-lang.org/issues/8671

Category: core
Target version: next minor


SEEK_DATA and SEEK_HOLE are whences for lseek(2) supported by Linux since version 3.1.
These are useful to deal with sparse files.
I propose that ruby supports these whences.
