alpine image needs groupmod and usermod

[Eirik A]

Found another dependency on docker images that I didn't know about:

/bin/sh: groupmod: not found
The command '/bin/sh -c groupmod -g 2000 lal && usermod -u 2000 lal' returned a non-zero code: 127
thread 'main' panicked at 'shell echoed', tests/testmain.rs:234:4

travis has uid 2000 and run into this using the alpine image in tests, so it will try to modify the group and user id of the lal user by using groupmod and usermod. These need to exist inside the containers.

Fixed in e7d62f6

New alpine image pushed just now.

However, this does not fix the alpine image..

because the alpine image does not have a lal group..

Fixed now.
