Update geant4 recipe

[ihrivnac]

Restore back the Modulefile variables removed in previous commit
and keep modifications for data sets

[ihrivnac]

@ktf, there are added back all variables which I removed from module file in the last update. Let's try this first, and if it does not help, we can then revert the file to the previous version completely.

@ktf, the geant4 recipe is now as before, and the builds end with Geant4 installation, which passes ok (what was also the case before reverting the recipe), and the check is marked as failed.

@kft,
I investigated the guntest failure on CC7, which caused the AliRoot PR failures after merging this PR, and the problems seems to be in aliBuild interpretation of the sed command used to defined the G4 data sets variables.
While in the recipe, there is:

G4ABLADATA : "${G4INSTALL}/bin/geant4-config --datasets | grep G4ABLADATA | sed 's/[^ ]* [^ ]* //'"
The aliBuild adds''around spaces:

DEBUG:AliRoot-guntest:AliRoot-guntest:0: +++++ /root/alice/sw/slc7_x86-64/GEANT4/v10.5.1-3/bin/geant4-config --datasets
DEBUG:AliRoot-guntest:AliRoot-guntest:0: +++++ grep G4ABLADATA
DEBUG:AliRoot-guntest:AliRoot-guntest:0: +++++ sed 's/[^' ']*' '[^' ']*' //
DEBUG:AliRoot-guntest:AliRoot-guntest:0: sed: -e expression #1, char 4: unterminated `s' command

The error can be reproduced in a terminal:

[root@o2tests02 alice]# /root/alice/sw/slc7_x86-64/GEANT4/v10.5.1-3/bin/geant4-config --datasets | grep G4ENSDFSTATEDATA | sed 's/[^]*[^]*' '//'
sed: -e expression #1, char 10: unterminated `s' command

while the original expression works fine:

[root@o2tests02 alice]# /root/alice/sw/slc7_x86-64/GEANT4/v10.5.1-3/bin/geant4-config --datasets | grep G4ABLADATA | sed 's/[^ ]* [^ ]* //'
/root/alice/sw/slc7_x86-64/GEANT4/v10.5.1-3/share/Geant4-10.5.1/data/G4ABLA3.1

Is there a way to tell aliBuild not to add the '' ?
Thank you.

I think the correct way of escaping strings in YAML is:

G4ABLADATA: | ${G4INSTALL}/bin/geant4-config --datasets | grep G4ABLADATA | sed 's/[^ ]* [^ ]* //'

@ktf, thank you, but this gives me the following errors:
