Undefined behaviour in abigail::tool_utils::string_ends_with.

Hi Doji,

Currently string_ends_with will crash if the suffix is longer than the
string. I've attached a patch that fixes this bug.

I discovered the bug by running abicompat ./a.out <lib1> <lib2>. This
command crashed because guess_file_type will call
string_ends_with("./a.out", ".tar.gz").
