Handle the case where either separated trailing input is empty or non-
existent by initializing the size to 0 and only call related code on
non-zero size.

Commit 89dd0b23 ("libselinux: avoid memory allocation in common file
label lookup") added an additional parameter to lookup_all() for an

Add two fuzzers reading and performing lookup on selabel_file(5)
databases. One fuzzer takes input in form of a textual fcontext
definition, the other one takes compiled fcontexts definitions. The
lookup key and whether to lookup any or a specific file type is also
part of the generated input.
