Remove module commands in favour of explict environment variables

[rtuck99]

Fixes #1426

Post 9.33+, GDA no longer has many variables in its environment and these are not exported to the run_hyperion.sh script when it is spawned. Therefore the script no longer has access to the module command and consequently ZOCALO_CONFIG is never defined because dials is never loaded.

Instructions to reviewer on how to test:

1. Hyperion can still start with latest GDA master
2. Hyperion can still start with previous GDA master

Checks for reviewer

• Would the PR title make sense to a user on a set of release notes

Change looks fine, thanks.

Fixes #1426

Does this mean that the beamline is currently using GDA master for everything? If not then we should probably either keep the original issue open until it is or make a new issue that is to make sure they've switched

They are still on "old master", however I went through the other gerrit changes in the ticket today and they are now all merged, so I believe this is the only thing preventing them moving up.
