refactor: remove goprocess (#10872)

* refactor: remove goprocess

The `goprocess` package is no longer needed. It can be replaces by modern `context` and `context.AfterFunc`.

* mod tidy

* log unmount errors on shutdown

* Do not log non-mounted errors on shutdown

* Use WaitGroup associated with IPFS node to wait for services to whutdown

* Prefer explicit Close to context.ArterFunc

* Do not use node-level WaitGroup

* Unmount for non-supported platforms

* fix return values

* test: daemon shuts down gracefully

make sure ongoing operations dont block shutdown

* test(cli): add TestFUSE

* test: smarter RequiresFUSE

opportunistically run FUSE tests if env has fusermount
and TEST_FUSE was not explicitly set

* docs: changelog
