Nightly build fails to build goansicolor for linux

Build is now failing for linux (i686 and x86_64), trying to build goansicolor:

Starting build (script: build): 2022-07-16 08:50:46
mv: cannot move '/var/tmp/build/goansicolor-a422bbe96644' to '/var/tmp/dist/gopath/src/github.com/shiena/ansicolor/goansicolor-a422bbe96644': Directory not empty
Finishing build (script: build): 2022-07-16 08:50:48

I think this is due to 777416b7, a space is missing before use_container in projects/goansicolor/config.

I didn't get the issue while testing the patch because I tested an alpha build, but goansicolor is only used by namecoin in nightly builds.
