build: fix for OS X avra 1.3.0

[liamstask]

i did not investigate the reason that avra on OS X cannot handle this formatting, but keeping everything uniformly formatted is nice, and has the pleasant side effect of fixing the OS X build.

Hmm I think this is probably related to the memory/heap corruption issues that were occurring on my 32-bit .deb build of avra 1.3.0. Would you be able to run avra in valgrind there (not sure about OS X) to see if it changes the output? We really should fix avra here...

Running in valgrind produces the same binaries, for the 2 that I checked. Output (only included the first file, but all subsequent files were processed successfully, and there was no further output from valgrind) pasted below:
