module function check does not support Environment Modules

[xdelaruelle]

When trying to use EB with Environment Modules, the module function check raises an error:

$ eb --modules-tool EnvironmentModules --module-syntax Tcl 
== Temporary log file in case of crash /tmp/eb-snqwtxzg/easybuild-gvwalsbq.log
ERROR: pattern '.*modulecmd.tcl' (Environment Modules) not found in defined 'module' function.
Specify the correct modules tool to avoid weird problems due to this mismatch, see the --modules-tool and --avail-modules-tools command line options.
Or alternatively, use --allow-modules-tool-mismatch to stop treating this as an error. Obtained definition of 'module' function: module is a function
module ()  
{ 
    local _mlredir=1;
    if [ -n "${MODULES_REDIRECT_OUTPUT+x}" ]; then
    |   if [ "$MODULES_REDIRECT_OUTPUT" = '0' ]; then
    |   ¦   _mlredir=0;
    |   else
    |   ¦   if [ "$MODULES_REDIRECT_OUTPUT" = '1' ]; then
    |   ¦   ┆   _mlredir=1;
    |   ¦   fi;
    |   fi;
    fi; 
    case " $@ " in 
    |   *' --no-redirect '*)
    |   ¦   _mlredir=0
    |   ;;  
    |   *' --redirect '*)
    |   ¦   _mlredir=1
    |   ;;
    esac;
    if [ $_mlredir -eq 0 ]; then
    |   _module_raw "$@";
    else
    |   _module_raw "$@" 2>&1;
    fi
}

Module command cannot be found in module shell function definition:

• starting version 5.1.0: module command is always called from _module_raw shell function
• starting version 4.0: module command is called from _module_raw shell function when it has been initialized in an interactive shell session

Defining a specific check_module_function function in EnvironmentModules class should be able to fix this issue.

I will provide such fix that tests _module_raw shell function prior module shell function.
