chore(cmdx): fix cmdx remove to be able to delete Docker container

[hituzi-no-sippo]

When the shell is not set, an error with sh will occur.

$ cmdx remove
+ set -euxo pipefail
docker stop -t 1 aqua-registry
docker rm aqua-registry

sh: 1: set: Illegal option -o pipefail
exit status 2

Suggested change

	set -euxo pipefail
	set -eux

I think we can simply remove the option -o pipefail.
This task doesn't use a pipe.
