Allow initialisation scripts to be used with bash < 4.2

[ocaisa]

If using a CentOS6 bash you get

-bash: /cvmfs/software.eessi.io/versions/2023.06/init/bash: line 4: conditional binary operator expected
-bash: /cvmfs/software.eessi.io/versions/2023.06/init/bash: line 4: syntax error near `EESSI_SILENT'
-bash: /cvmfs/software.eessi.io/versions/2023.06/init/bash: line 4: `  if [[ ! -v EESSI_SILENT ]]; then'

-v was introduced in Bash 4.2, but it's not hard for us to improve our backwards compatibility

Probably worth a review but I will set the label anyway...
