[PATCH] config.sub: add Managarm support

[Dennis Bonke]

---
Dear maintainers,

I would like to submit a few new targets to config.sub, namely Managarm.
Managarm is a FOSS microkernel with fully asynchronous I/O and runs
on or has ports in progress for x86_64, aarch64 and risc-v. It can be
found on https://github.com/managarm/managarm. This is my first time
submitting any kind of patch to a GNU project so if there is anything I
forgot in the patchset please let me know so I can fix it.

Kind regards,

Dennis Bonke
Managarm package maintainer
https://managarm.org
