Change the env in which esgf-dashboard-ip --version is called...

The issue may be with the LD_LIBRARY_PATH
I believe it may need to have /lib${word_size} early in the
path. (still needs testing to confirm)

Note:

When calling from the prompt (tantamount to what is happening in the
script, you get)

esgf-dashboard-ip: /usr/local/uvcdat/Externals/lib/libxml2.so.2: no version information available (required by esgf-dashboard-ip)
esgf-dashboard-ip: /usr/local/uvcdat/Externals/lib/libxml2.so.2: no version information available (required by esgf-dashboard-ip)
1.3.7

by stripping the err output you get what we should get.

1.3.7

So for now we will have the version command be explicit and send
stdout to /dev/null to give us the desired effect.
