[PATCH] Fix -Wformat-length warning in tst-setgetname.c

[Steve Ellcey]

Here is another patch to fix a new warning (-Wformat-length) coming
from GCC 7.0.  If GCC thinks an snprintf might overrun the buffer being
written to, it gives a warning.  This patch increases the buffer size
so that the warning is no longer given.

OK to checkin?
