test: Skip some test on OSX arm64

There is a weird error running on my macbook apple silicon based where
ordering is totally different than when running on other platform (ie:
Linux).

I can't figure out why this is happening but i am guessing some bug in
the Golang compiler.

The error shows:

queue_manager_test.go:135: assertion failed: test-ns/fifth (started[0]
string) != test-ns/fourth (string)

and that randomly happen.
