#2940: Fix edg-mkgridmap PRIMA check

> On a 64-bit install, gums-host-cron doesn't properly detect that prima
> is being used and will overwrite any existing grid-mapfile. This breaks
> other applications that use the grid-mapfile, such as condor with
> x509-based authentication.
>
> The problem is line 347 in gums-host-cron:
>
> PRIMA_CALLOUT_STRING="libprima_authz_module_gcc32dbg"
>
> On 64-bit installs, this should be:
>
> PRIMA_CALLOUT_STRING="libprima_authz_module_gcc32dbg"
>
> --Mike

>Jay,
>I don't think we even need to be that accurate on it. The string...
> libprima_authz_module_gcc
>.,, should be sufficient for now.
>
>Alain,
>This also needs to be changed in the this script.
