fuzz: simplify fuzzers dependencies in CIFuzz (#1896)

CIFuzz (based on oss-fuzz) is the GitHub action/CI job that runs fuzz
targets on pull requests. It only runs the fuzzers affected by a pull
request/commit. Otherwise it will divide up the allotted fuzzing time
among all fuzzers in the project.
Since:
* we have more than 20 fuzzers and most of them use the custom memory
allocation functions (to force allocation failures) even if they are not
strictly about DPI stuff;
* we need to keep fuzzing time relatively small (to avoid waiting the CI
results for a long time)

it is important that fuzzers dependencies (which are based on *files*
changed by the single commit/PR) are as small as possible.

Bottom line: move all the low-level allocation callbacks to a dedicated
file; this way most of the fuzzers don't depend anymore on `ndpi_main.c`
file (which is touched by ever commit/PR).

The goal is to have only the "most important" fuzzers running during (most
of) the CI.
