Tiny I/O Nice

This is a fork of ionice from util-linux, in just 324 lines of C.

The support for obsolete systems is removed.
The translated output messages are removed.
Other than that it's a fully featured drop-in replacement of ionice.
The resulting executable is only 11k when built with GCC 11 on Linux (and then stripped with sstrip).
util-linux uses several open source licenses across many different files. This fork is only based on files licensed under GPL2. tinyionice is only GPL2 licensed.
