[PATCH liburing v1 2/2] .gitignore: Add compilation database file and directory

[Haiyue Wang <haiyuewa@163.com>]

The tool 'bear'[1] can be used to generate the C language server protocol
database file while compiling: 'bear -- make -j $(nproc)'

Add the database file into .gitignore as Linux Kernel [2] does.

The clangd will parse the compile_commands.json language metadata into the
.cache directory. Add it for clean git status track.
