Singularity module now loads hidden modules.

[dipietrantonio]

The generated singularity module file now loads dependency modules, although no explicit autoload was set.

load(".cryptsetup/2.3.5-nmbjwez")
load("go/1.17.2")
load(".libgpg-error/1.46-5vso6hb")
load(".libseccomp/2.3.3-6m45xkp")
load(".shadow/4.8.1-4nbhlhp")
load(".squashfs/4.5.1-4dn2dwq")
load(".util-linux-uuid/2.38.1-mvepyq3")

Need to check whether this is true also for other packages.

In addition, the scripts/create_custom_singularity_modules.sh, when creating the no-mpi module, removes also parts of the module file that check for directory permissions and enforce the use of versions.

I suspect there is an error in the following sed command:

-e '/MPI + Singularity configuration/,/singularity_ld_path *= *singularity_ld_path/d' \

It references singularity_ld_path but I do not see that string anywhere in the original module file.

Also, we should mount /scratch and /software also in the no-mpi version.
