Subject: oss-fuzz: sync build script with upstream

File copied from https://github.com/google/oss-fuzz/blob/master/projects/ndpi/build.sh

The general idea is to keep the build script in our repository and use
it from oss-fuzz builder: updating it from our side is easier and faster
then passing via an oss-fuzz PR.

The original idea is from @utoni in 3068306b60.

Once this change has been merged, we can update the code in oss-fuzz.
