[PATCH] build: avoid shadowed variable in fdstreamtest

[Eric Blake <eblake@xxxxxxxxxx>]

On RHEL 6.4 (gcc 4.4.7), I got:

fdstreamtest.c: In function 'testFDStreamReadCommon':
fdstreamtest.c:44: error: declaration of 'tmpfile' shadows a global declaration [-Wshadow]

* tests/fdstreamtest.c (testFDStreamReadCommon)
(testFDStreamWriteCommon): Rename 'tmpfile' variable.

Signed-off-by: Eric Blake <eblake@xxxxxxxxxx>

Pushing under the build-breaker rule.
