snprintf truncation error in lalapps/src/pulsar/HeterodyneSearch/ppe_readdata.c

gcc 8.3.0 on my new Debian Buster laptop finds another string length issue that not even the nightly pipeline has picked up so far, this time in lalapps/src/pulsar/HeterodyneSearch/ppe_readdata.c . Should be easy to fix, @matthew-pitkin could you have a look please?
