Carlos O'Donell ea8e2b96d8 nss: Add ERANGE testing to tst-nss-test4 (bug 33361) ...

This adds testing for the fix added in commit:
0fceed2545
"nss: Group merge does not react to ERANGE during merge (bug 33361)"

The in-use group size is increased large enough to trigger ERANGE
for initial buffers and cause a retry.  The actualy size is
approximately twice that required to trigger the defect, though
any size larger than NSS_BUFLEN_GROUP triggers the defect.

Without the fix the group is not merged and the failure is detected,
but with the fix the ERANGE error is handled, buffers are enlarged
and subsequently correctly merged.

Tested with a/b testing before and after patching.
Tested on x86_64 with no regression.
