Add possibility to globally include n98-magerun modules

[norgeindian]

According to https://github.com/netz98/n98-magerun2/wiki/Modules#where-can-modules-be-placed it is possible to add modules for n98-magerun.
I tried to put them into /usr/local/share/n98-magerun2/modules and ~/.n98-magerun2/modules, but in both cases n98-magerun did not find them. Either I did something wrong or the folders are not synced into the container.
Would it be an idea to add them in general, so that modules can be used?

This is great to have.
Also, I was looking for the same for globally including the bash script in all the php-fpm containers.
