suricata: clean some disk space while building

[catenacyber]

As done by openssl in #11618

Is there a way from build.sh to know if we are built by CIFuzz ? Like environment variable CFL_PLATFORM ?
Because I do not think we want to build other branches than master for CIFuzz

You can use the CIFUZZ environment variable for this.

Thanks @kleisauke cf #11800

This seems to have broken coverage build despite green CI cf https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=68045

make clean removes some generated code files like `gen/rust-bindings.h' so we get

Step #5: �[0m�[0;31merror: /workspace/out/libfuzzer-coverage-x86_64/src/suricata7/rust/gen/rust-bindings.h: No such file or directory

Fix pushed in #11800
