test_get_sendfile_http2 and test_get_sendfile_http2_direct use same temp file

[maru]

Reported by @rockdaboot : Another issue, one of the test_get_sendfile_http2/test_get_sendfile_http2_direct tests fails here. Reason was that both create and delete the same temp file. If run in parallel, there was a race condition. Fix was to use diferent file names:
