t9824: fix wrong reference value

0492eb48 (t9824: fix broken &&-chain in a subshell, 2016-04-24)
revealed a test that was broken from the beginning, as it expected a
wrong size.  The expected size of the file under test is 39
bytes. The test checked that the size is 13 bytes, but this was not
noticed because it was breaking the &&-chain.

Fix the reference value to make the test pass.
