Tiny I/O Nice

This is a fork of ionice from util-linux

It's a drop-in replacement for ionice in just 300 lines of C and under a single open source license.

• Support for obsolete systems is removed.
• Translated output messages are removed.
• Other than that it's a fully featured drop-in replacement for 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.
